Those who believe salvation can be lost often ask an insightful question about the relationship between salvation and faith. The question goes something like this: If our salvation is gained through believing in Christ, doesn’t it make sense that salvation can be lost if we quit believing?

To answer this question, we must see what saves us. Paul tells us that we are saved by grace (Eph. 2:8–9). The instrument of salvation is grace. God came up with a plan and carried it out through Christ. We didn’t take part in it; we didn’t deserve any part of it. It was grace from start to finish. We are saved by grace through faith. “Through faith” is important, but often misunderstood. “Through” is translated from the Greek word dia, which carries the idea of “means” or “agency.” Faith was the agent whereby God was able to apply His grace to the life of the sinner.

Faith is simply the way we say yes to God’s free gift of eternal life. Faith and salvation are not one and the same any more than a gift and the hand that receives it are the same. Salvation stands independently of faith. Consequently, God does not require a constant attitude of faith in order to be saved—only an act of faith in Christ.

You and I are not saved because we have enduring faith. Faith is not a power we tap into or a button we push to prod God into action. Rather, faith is confidence that God will do what He has promised. We are saved because we’ve expressed trust that the Lord Jesus has really saved us.
