Good News For Broken Hearts - Podcast

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).
