Many Christians fear that they have not been forgiven by God because they have not yet been able to fully forgive others. They want to forgive, but they still have negative feelings towards those who have hurt them.
They can easily be condemned by what Jesus is saying in Matthew 18:35, that if we do not forgive our neighbor with our heart, God will not forgive us, but reject us and punish us, which makes us have the fear that God has not forgiven us. I often skipped this scripture and was afraid of it myself, I wished it was not there because I feared that I had not forgiven all who have hurt me perfectly, but now I have seen something I want to show you, and I will give you an answer to why Jesus said what he said.
What about the first letter of John saying that God does not forgive us before we have confessed our sins? If we confess our sins, he is faithful and just, so he forgives us from sin and purifies us from all unrighteousness.
This is a scripture many use to explain that God has not forgiven us until we have made up for our sin and asked for forgiveness. It may seems, when we read this, that God has not forgiven us until we do the next sin and that we constantly must remember to ask forgiveness to remain forgiven, but is this so?
Am I forgiven if I have forgotten to confess a sin or sins? If I have done a sin, am I only forgiven until I do next sin and have asked forgiveness for it? Does God only forgive me for the sins I have remembered to confess? Does God hear my prayers if I have not totally forgiven someone?
I know there are many Christians who are afraid that they may not be forgiven, and many think of what Jesus said in the Sermon Of the Mount in Matthew 6:15, where Jesus says that God can not forgive you until you have forgiven others (perfectly).
