We attribute the sacrifice of Jesus as the means to our salvation, and we look to the evidence of the Resurrection as the completion of his work. But there is rarely mention of the Holy Spirit’s role in our salvation. Without the work of Jesus we cannot obtain salvation, but without the work of the Holy Spirit we cannot obtain salvation either. To understand this is to fully understand salvation as well as the Holy Spirit’s further roles He can play in our lives.
Before discussing the role of the Holy Spirit, let us first look at the work of the Father and Son in salvation. Beginning with what is undoubtedly the most widely-memorized scripture, John 3:16, we find the purpose for Jesus coming to earth.
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. For God did not send his Son into the world to condemn the world, but to save the world through him. Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son. This is the verdict: Light has come into the world, but people loved darkness instead of light because their deeds were evil.Everyone who does evil hates the light, and will not come into the light for fear that their deeds will be exposed. But whoever lives by the truth comes into the light, so that it may be seen plainly that what they have done has been done in the sight of God (John 3:16-21).
Jesus proved himself as the Messiah and son of God time and again. In fact, the book of John’s main theological emphasis was Jesus as Son of God. It was Jesus’ claim as being God, as well as being the Son of God, that condemned him to death on the cross. But it was the plan of God the Father all along, that his only son would shed his blood for the sins of the world (2 Cor. 5:21). Here, in the third chapter of John, we see two of the three members of the Trinity acting in salvation—the Son carrying out the plan of the Father.
