Yes, completely. There is no sin the cross left uncovered, and no condemnation for you in Christ. Your standing with God is not defined by your worst day.
The Grace Answer
If you are reading this, you may have carried something heavy for a long time, maybe in silence, maybe for years, maybe every single day. So let the first word be the truest one. You are not beyond His reach, and you never were, not for a moment.
Look at what the cross actually did with your sin. God made you alive together with Christ, having forgiven you all trespasses. Not some. All. He wiped out the record of debt that stood against you and nailed it to the cross, out of the way for good. That includes the thing you can barely say out loud. It was not the one item left off the list. It was placed on Jesus with everything else, and He carried it all the way down.
As far as the east is from the west
David wrote that God removed our transgressions from us as far as the east is from the west, a distance with no meeting point and no road back. Through Isaiah, God said that though your sins are like scarlet, they shall be as white as snow. That is not God grading you gently or looking the other way. It is God lifting the guilt and the condemnation off you completely, even when grief, memory, and the long work of healing remain part of your story. There is therefore now no condemnation to those who are in Christ Jesus. None for you.
Your story may hold things you rarely say aloud. Pressure, coercion, abandonment, fear, a moment you felt you had no way through. God is not standing over any of it with crossed arms, waiting for you to produce enough sorrow to earn your way back. He is holding you. Grief may still visit, and that is human and even holy, but grief is not the same as condemnation, and the two must never be fused. The forgiveness is finished, not pending your penance. You do not have to buy back a place you never actually lost. You are His, fully and freely. Whatever voice has told you otherwise, it is not His. His word over you is finished, and it is good.
