You need to get this deep into your heart. The old you, your past problems, and your past motives have passed away. Everything concerning your life is made brand new.
This is the very reason we must die to self and crucify the flesh. Today you must realize that you are no longer guilty of your past. No matter what you did or how many people that you hurt along the way.
Do not let the enemy convince you that you are not a new creation, and don't let how people feel about you because of what you did to them bring condemnation (Romans 8:1). You cannot change anything from your past. Your past failures belong to the Father.
Hold your head high, and go boldly to the throne of grace; not in arrogance, but humbly knowing it's the Spirit in you that has brought change.
It's time to stop focusing on your problems, your past and self proclaimed inadequacies. Focus only what the Father is doing in you. Walk in obedience and doors that you or anyone could not open will be opened to you. Be subject to His will and you cannot fail!

“Now, if anyone is enfolded into Christ, he has become an entirely new person. All that is related to the old order has vanished. Behold, everything is fresh and new. And God has made all things new, and reconciled us to himself, and given us the ministry of reconciling others to God. In other words, it was through the Anointed One that God was shepherding the world, not even keeping records of their transgressions, and he has entrusted to us the ministry of opening the door of reconciliation to God.” (‭‭2 Corinthians‬ ‭5‬:‭17‬-‭19‬ ‭TPT‬‬)
