Stefina, please trust yourself and the past to God. This is what He says in the bible.
“Jesus Christ…is the sacrifice that takes our sins away, and not only ours, but the whole world.” [1John 2:1-2]
Our God, You sent Your Son “into the world, not to condemn the world, but so that through Him the world might be saved. No one who believes in Him will be condemned.” [John 3:17-18]
You assure us through Isaiah, our God,
“I have dispelled your faults like a cloud
your sins like a mist
Come back to me, for I have redeemed you.” [Isaiah 44:22]
Furthermore, You proclaim:
“Happy those whose crimes are forgiven, whose sins are blotted out; happy the man whom the Lord considers sinless.” [Psalm 31:1-2] For through Your Son, You have “**cancelled every record of the debt that we had to pay; He has done away with it by nailing it to the cross.” **[Colossians 2:14-15]
Therefore, our God it is not presumptuous to ask that we may be healed of our faults and freed from our sin. Indeed, You have said:
“No need to recall the past,
no need to think about what was before.
See I am doing a new deed,
even now, it comes to light; can you not see it?
Yes, I am making a road in the wilderness,
paths in the wild.” [Isaiah 43:18-19]
Although we must strive through the Spirit to walk the way of Your Son, You assure us that we are not alone or dependent upon our efforts alone:
**“For I, … your God,
I am holding you by the right hand;
I tell you, do not be afraid, I will help you.
Do not be afraid…poor worm…
the Holy One of Israel is your Redeemer.” **[Isaiah 41:13-14]
