How can I have assurance of my salvation?
This is a common question many Christians have. I think it stems from the reality that we are saved by grace through our faith. In the minds of most people (for many years this described me as well), being “saved by grace through faith” feels like salvation was out of our hands. This means salvation is a gift from God, and we receive this great and wonderful gift through our belief.
The problem with viewing salvation this way is that there is no tangible standard for us to know that we have truly received the gift of salvation. If it was based on what we did, at least we could keep a score card on our behavior so we could know if we were living up to the right standard.
Without a tangible standard, many people rely on a subjective experience to tell them that they are saved. The problem with this is that over time the feeling of the experience fades, and we are left with the same question: Am I saved?
Life is going to take us through a series of ups and downs. In one moment we feel like we are close to God and that our salvation is secure, but the next moment we wonder if God has abandoned us. If we are going to rely on a subjective experience as evidence for our salvation, then we are going to constantly doubt our salvation. What we need is an objective standard to tell us that we are saved, and thus give us confidence of our salvation. - See more at Assured of Salvation.
