Sadly, there are far too many people who get tied up with their wrongs and dwell in worthlessness, or feel like they are a horrible person. You are not a horrible person; you are simply a person. God wants us to recognize our faults and repent, ask forgiveness and understand what we’ve done wrong. It’s important to repent of the things we do in order to grow. It’s when we continue to abuse God’s grace, via not repenting or not changing, that it gets scary. I believe there are particular ways God handles His children and their disobedience. He is a father to us, so naturally He disciplines his children in ways we wouldn’t want to happen. Thankfully, God always choose mercy before judgement. Nevertheless, that does not make him a doormat, nor does it give us an excuse to use his grace as a “license for immorality” (Jude 1). So, it’s a very serious thing when we abuse grace, don’t repent, or continue living out our sin and overlooking those small tug on our hearts.
We have to make drastic changes to overcome. We have to repent, remain humble, and we will grow stronger. Don’t let yourself get beat up by the past, but make a change for the future. The grace of God is with you, but be weary to not abuse it.
