You are a strange type of Christian or your church has a strange doctrine. We are forgiven by accepting Christ and God’s grace. If you feel you have to ask forgiveness constantly you are either 1. not living your faith or 2. disbelieving in your forgiveness.
As someone who has been saved by Christ’s death on the cross, I have no doubt I am forgiven my sins.
Have you ever confessed your sins to God, and asked His forgiveness? Is doing so heresy? Is it wrong to humble yourself thus before your Creator? Is it wrong to believe that I need a Savior ... today?
