In the previous post we introduced the question about what did salvation in the Old Testament look like and was faith in Jesus needed to be saved. We introduced the topic in that post and will further clarify the response in this one.
Individuals in the Old Testament period were saved by grace through faith. Salvation has always been by grace through faith in Christ (Eph 2:8-9); it has always been in Christ and is based on His sacrifice. “The basis of salvation in every age is the death of Christ. The sacrifices pointed forward to the death of Christ in the future. The requirement for salvation in every age is faith. The object of faith in every age is God. It’s the content of faith that changes in the various dispensations.” Throughout the Old Testament we see God’s promise of a Messiah (Gen 3:15; Isa 9; 53), but it was historically impossible to have Jesus as the content of their faith. The concept of faith has always been important because “without faith it is impossible to please” God (Heb 11:6), and it is displayed in the lives of both Old and New Testament believers. It seems that Old Testament individuals did not understand the “redemptive significance” of the prophecies concerning Christ and His suffering, nor is it apparent that they understood that the sacrifices depicted the person and work of Jesus Christ as the church age believers do. The sacrifices of the Old Testament pointed toward the sacrifice of Christ and those done in faith brought temporary forgiveness (Ps 32:1-2; 103:12) because of the sacrifice of Christ that was to come.
“Those who have faith are blessed along with Abraham, the man of faith” (cf Gal 3:8-9 with Gen 12:3). In Galatians 3:11, Paul quotes Habakkuk 2:4 saying “the righteous shall live by faith.” Hebrews 11 displays the faith of the Old Testament believers was evident as Scripture says their faith was “counted to them as righteousness,” (Gen 15:6; Rom 4:3, 5-8; Heb 11:7). The Old Testament people had the promise of the coming Savior and that He would “save His people from their sins” (Matt 1:21; cf. Isa 53:5-6). The people of the Old Testament were saved in the same way we are today, by faith in the Savior. For the Old Testament believer it was the promise of the Messiah because God had only revealed a certain amount to the people of the Old Testament period.
The difference between the faith of the Old Testament believer and a New Testament believer is the content of faith. Thus, God’s requirements for what must be believed is different based on the amount of revelation He has given. Since Jesus is the fulfillment of God’s promise, He has given us a more complete revelation of the Messiah in the life, work, death, and resurrection of Jesus. Salvation has always been by grace alone through faith alone in Christ alone. Therefore, did individuals in the Old Testament period did need to know about Jesus to be saved? Yes, individuals were saved by grace through faith in Christ based on what God had revealed about the promised Messiah, Jesus, who would bring complete atonement. Since we have the complete picture, our salvation is based on the death of Christ, our faith is the requirement, and the object of faith is God. The content of our faith is different than Old Testament believers because we know that Jesus came to this world, died for our sins, was buried, resurrected, and will return one day.
