Work of the Son—The contribution of “the Son” is characterized by His obedience to “the Father” by practically offering his life as a ransom for many (Mk. 10:45). Jesus became our sin (2 Cor. 5:21) and was crushed in our place (Isaiah 53), so that we could be reconciled to the Father. Jesus was already reconciled to the Father due to the fact that he had never broken the Father’s law/will (1 Pet. 2:22). The creator was incarnated into a fleshly man so that he could demonstrate to the world who the Father is (Heb. 1:3), what unity with the Father actually looks like (John 17), and to satisfy the wrath of God thereby providing a way to actually have eternal life with the Father (Rom. 3:25-26).
Work of the Spirit—The contribution of “the Spirit” is characterized by His convicting people of their sin, demonstrating that Satan’s power is subdued, and dwelling within those who believe in Jesus as proof that they are saved from the judgment of God and empowered to walk in the good works that God has preordained for each believer (Eph. 2:10). Jesus talked about the Spirit in John 16:8-11 saying “And when he comes, he will convict the world concerning sin and righteousness and judgment: concerning sin, because they do not believe in me; concerning righteousness, because I go to the Father, and you will see me no longer, concerning judgment, because the ruler of this world is judged.” Finally, “sanctification is the work of the Holy Spirit…it is the Spirit who is at work in the believer, bringing about likeness to Christ.” The epistle to the Galatians talks specifically about how we are to “walk by the Spirit” and then goes into detail how doing so unifies us with our savior and pulls away from the old man who once condemned us. This process of sanctification is not conditional, but rather consequential of a life ransomed by Jesus.
Assurance of Salvation—Is simply defined as “a belief that Jesus Christ is in your life”. Our assurance is based on the actual belief for what Christ has done for us. Secondly, we actually begin to look like the Father. Third, it is that we are disciplined in being sanctified. The assurance of salvation is based on our faiths not by our works.
Evidence of Salvation–Evidence is best characterized as the way that other people sense that we are saved. The evidence of salvation is the flip side of the assurance of salvation—it is the works that we notice in the individual’s life that align with their beliefs. The presenter uses the analogy of a fruit inspector to describe how people can analyze the marks of salvation in others.
Security of Salvation—The peace that is in our lives is the mark of those who are saved. Romans 8 discusses how there is nothing that can separate us from Christ and that there is no condemnation for those who are in Christ. We should not feel like it is dependent upon us to remain in Christ. While our sanctification is a mark of our salvation, it is not the degree of our sanctification that determines how saved we are. We have either put on the robes of righteousness which is Christ, or we are wearing improper wedding garments which will get us thrown out at the wedding feast (Matt. 22).
