Soteriology Lesson 45 - What Must I Believe to Be Saved?

The Terms of Salvation

God requires that certain information be received and believed before He saves someone. This means saving faith requires content. From the divine side, God has done several things to bring about our salvation. From eternity past it was planned by God the Father (Eph 1:4; 2 Tim 1:9; 1 John 4:9-10, 14), executed in time by God the Son (John 3:16; Mark 10:45; Luke 19:10), and applied to those who believe by God the Holy Spirit (John 3:6; 1 Cor 12:13; Gal 3:27; Tit 3:5; 1 Pet 1:3). It was necessary that God the Son come into the world in hypostatic union, as undiminished deity and perfect humanity (John 1:1, 14; Col 2:9; Heb 1:8; 10:5; 1 Pet 2:24), be born of a virgin (Isa 7:14; Luke 1:30-35), live a sinless life (2 Cor 5:21; Heb 4:15; 1 Pet 2:22; 1 John 3:5), willingly go to the cross (Isa 53:10; John 10:11, 17-18), die a penal substitutionary atoning death on behalf of all humanity (Rom 5:8; 1 Cor 15:3-4; Heb 2:9; 10:10-14; 1 John 2:2), and be buried and resurrected on the third day (Matt 16:21; Rom 6:9; 1 Cor 15:3-4; 12-20). This was done to satisfy God’s righteousness and justice regarding our sin (Rom 3:25; 1 John 2:2), and to display His love for us as lost sinners for whom Christ died (John 3:16; Rom 5:8). This was necessary because we are totally corrupted by sin and helpless to save ourselves (1 Ki 8:46; Eccl 7:20; Isa 59:2; 64:6; Rom 3:10, 23; 5:12; Eph 2:1-2; Jam 1:14-15), and if God had not acted in love (John 3:16; 1 John 4:9-10), we would all be damned forever to the lake of fire (Rev 20:15).

God, who is infinitely loving, good, and gracious, offers us salvation freely, as a gift (Rom 3:24; 6:23), by grace (Eph 2:8-9), and conditions it on faith alone in Christ alone (John 14:6; Acts 4:12), and “not as a result of works, so that no one may boast” (Eph 2:9; cf., Rom 11:6). According to Lewis Chafer, “salvation in all its limitless magnitude is secured, so far as human responsibility is concerned, by believing on Christ as Savior. To this one requirement no other obligation may be added without violence to the Scriptures and total disruption of the essential doctrine of salvation by grace alone.”[1] Charles Ryrie adds:

• "More than 200 times in the New Testament, salvation is said to be conditioned solely on the basis of faith—faith that has as its object the Lord Jesus who died as our substitute for sin (John 3:16; Acts 16:31). Salvation is a free gift; therefore, any statement of the terms must carefully avoid implying that we give God something. He gives it all; we receive that gift through faith (John 1:12)."[2]

John Walvoord states:

• "The terms of salvation are limited to faith in Christ because of the inadequacy and insufficiency of any other approach. Salvation is pictured therefore as a gift (Rom 6:23), as obtained by those “dead through … trespasses and sins” (Eph 2:1). Salvation is therefore not a work of man for God or a work of God assisted by man, but rather a work of divine salvation effective on those who are willing to receive Jesus Christ as Savior."[3]

J. Dwight Pentecost states:

• "The gospel is characterized by its simplicity. When the Apostle Paul declared the terms of salvation to the Philippian jailer, he said “Believe on the Lord Jesus Christ, and thou shalt be saved …” (Acts 16:31). The Apostle Peter, speaking concerning salvation, declared, “… there is none other name under heaven given among men, whereby we must be saved” (Acts 4:12)—none other but the name of Jesus. Sinners, confronted with their need of salvation, frequently stumble over the very simplicity of the salvation which God offers. Since Satan cannot take away anything from the conditions of salvation or the plan of salvation—for God has already reduced it to an irreducible minimum—if Satan is to confound the minds of the sinners he must do so by addition, not subtraction. If conditions were placed by God to salvation, Satan might take away those conditions so that men would not be saved. But since there are no conditions, and salvation is a simple fact to be believed, Satan’s method of deceiving men has been to add to the simplicity of the gospel. That is why some will teach that salvation is by faith and good works; or, salvation is by faith and baptism; or, salvation is by faith plus church membership; or, salvation is by faith plus repentance. These are all attempts to darken the mind of the man who needs to be saved concerning the central issue and the basic plan of redemption."[4]

Though faith alone is the only requirement by God, the content of faith has changed throughout the ages, depending on what God revealed at a particular time. What God revealed to Adam and Eve was different than what He revealed to Abraham, and what He revealed to Abraham was different than what He reveals to us. Before addressing the content of saving faith, let’s look at what it means to believe.

What it Means to Believe

The word believe, in the OT, derives from the Hebrew verb aman (אָמַן) which means “to regard something as trustworthy, to believe in.”[5] And in the NT, the Greek verb pisteuō (πιστεύω) means “to consider something to be true and therefore worthy of one’s trust.”[6] In Genesis we see where Abraham “believed [aman] in the LORD; and He reckoned it to him as righteousness” (Gen 15:6). When citing this passage in the NT  (Rom 4:3; Gal 3:6; Jam 2:23), the writers used the Greek verb pisteuō (πιστεύω) in place of the Hebrew verb aman (אָמַן), which shows the words are synonymous. Faith, as a verb, is used of trust in God (Gen 15:6; Heb 11:6; cf. Rom 4:3), trust in Jesus (Acts 16:31; 1 Pet 1:8), and trust in Scripture (John 2:22).[7]Biblically, faith means having an attitude of confidence in God, being certain that He will keep His Word and do as He promised, for He cannot lie (Num 23:19; Heb 6:18; Tit 1:2). When faith is exercised, it trusts solely in the object and no one else. Abraham is an example of a believer who trusted God at His Word, for “with respect to the promise of God, he did not waver in unbelief but grew strong in faith, giving glory to God, and being fully assured that what God had promised, He was able also to perform” (Rom 4:20-21).

To believe is to have a mental conviction that a testimony is true or that someone or something is reliable and worthy of confidence. Faith starts with mental assent and results in placing one’s faith in the object itself. For example, one can assent that a chair is structurally sound and able to support a person, and then, by faith, sit in the chair and relax. Or one can assent that an automobile is safe to drive, and then, trusting the car, get behind the wheel and drive it to a desired destination. Faith always demands an object, is exercised with a view to receiving a benefit, and the object gets the credit for doing what it was supposed to do. For Christians, Jesus is the object of our faith, eternal life is the benefit we receive, and Christ gets all the glory as the One who saves. When we believe in Jesus, we acknowledge that He is the incarnate Son of God (John 1:1, 14), that our salvation was accomplished by means of His death, burial, and resurrection (1 Cor 15:3-4), and we trust in Him alone to save us eternally (Acts 4:12; 16:31). Christ alone saves. Nothing more. The following illustration is helpful:

• "Many people misunderstand what the Bible means by “believe.” Belief basically means trust. As an example, imagine you are stranded on one side of a river. The only way across is via a tightrope suspended overhead. A man on the other side has a wheelbarrow and says he can rescue you. Being a skilled acrobat, he crosses the tightrope with the wheelbarrow successfully. Now, you believe that the man himself can cross the tightrope, but in order to be saved, you have to trust him to get you over the tightrope in the wheelbarrow! Will you believe in him or not? Similarly, trusting Jesus for salvation means trusting him to do for you what you cannot do for yourself. There’s no way we can earn heaven; we must trust Jesus to carry us there."[8]

[7] The NT also presents faith as a noun (πίστις pistis), which often refers to “that which evokes trust and faith…the state of being someone in whom confidence can be placed, faithfulness, reliability, fidelity” (BDAG 818). The word is used with reference to God who is trustworthy (Rom 3:3; 4:19-21), and of people who possess faith (Matt 9:2, 22; 21:21), which can be great (Matt 15:28; cf. Acts 6:5; 11:23-24), small (Matt 17:19-20), or absent (Mark 4:39-40; cf. Luke 8:25). It is also used of Scripture itself as a body of reliable teaching (i.e. Acts 14:22; 16:5; Rom 14:22; Gal 1:23; 2 Tim 4:7). And we see faith as an adjective (πιστός pistos), which describes someone “being worthy of belief or trust, trustworthy, faithful, dependable, inspiring trust/faith” (BDAG 820). The word is used God (1 Cor 1:9; 10:13; 2 Tim 2:13; Heb 10:23; Rev 1:5), and of people (Matt 25:23; 1 Cor 4:17; Col 1:7; 1 Tim 1:12; 2 Tim 2:2; Heb 3:5).
