God is excellent at giving opportunities to people where the important thing for him is the present because he calls you and wants you to transform your life because he forgets the past and works with the present.
So when God calls you and you hear him God restores your present and never again remembers your past but if God does not remember much less should you remember because you must live a new life.
2 Corinthians 5:17
17 So if anyone is in Christ, he is a new creation; old things have passed away; here they are all made new.
(RVR1960)
Through faith and through the resurrection of our Lord Jesus Christ we become a new creature and practice all new things established by the word in obedience to God.
Likewise, God has promised to give us a new heart according to the spirit to change our lives and forget the past
Ezekiel 36:26 “I will give you a new heart and put a new spirit within you; I will take away the stony heart out of their flesh and give them a heart of flesh. "
Through this new life and this new present, God will give you a new heart that is sensitive and open to the teachings, the opposite of a heart of stone, and will renew your mind and spirit to strengthen each step of your new path.
Your past is no longer important to God. No matter what you've done, God has forgiven you. In God you will find hope and practical advice to keep moving towards the wonderful future that He has in store for you.
Isaias 43:25
I, I am the one who blots out your transgressions out of love for myself, and I will not remember your sins.
(The New American Bible)
God has promised man a life full of love, peace and hope and it is through Jesus Christ that he will help you change your life to change the past and leave behind everything that has prevented you from having a relationship with Him
