Friend, never forget that the Word of the Lord tells us that in Christ Jesus we have Redemption thru Christ blood, even THE FORGIVENESS OF SINS (Colossians 1:12-14). WE HAVE IT says the Lord. It is part of our redemption inheritance. It is part of the redeeming riches of His glory given us all freely by His most powerful sacrifice, by the sacrifice of Himself. It is written, By the sacrifice of Himself, Jesus overcame and put away sin. That is shouting territory.
Christ did not die in vain, but to make us rich in all His life's beauty, glory, goodness, love, joy, peace, and mercies, here and for all eternity. Rich in them one and all now and forevermore.
Friend God is rich in mercy. He is your Father in Christ. This makes you rich in the forgiveness of your sins. I don't care how bad your sin or sins are in your mind. Your rich Father is exceedingly abundantly far more richer in mercy and love than all the sin of all the world. So He most certainly can handle your and my sins, though they are many.
