Amen, he declares "the end from the beginning". But consider that the reason we confess our sins to God is not so that He knows we've done wrong, but to humbly show that we know that we've done wrong. Since you don't know what sins you may commit in 2021, you can't confess them until then.
There's a reason the Catholic church loves to depict Martin Luther as a drunkard. More than once, the enemy wore down Luther in his fight against the devil's agents of his Vatican headquarters, and Luther found himself seeking consolation in a bottle of booze. But I defy any man to argue that Luther was not a spiritual giant among giants, and in a class all his own when compared to the leadership of today's Laodiceans. The difference is that Luther was "a just man" who fell seven times and rose up again. There's always grace for that man, but never for any saint who ceases to walk with the Son and the Father because he failed to let remain that which he had heard from the beginning. (1 John 2:24 KJV) God bless you too.
Luther is an interesting case. Certainly he revived a debate, but between his hatred of the jews and desire to throw out books of the Bible there is grounds for questioning if he truly understood grace. He is definitely a giant in the history of doctrine but the offspring of the reformation are rather mixed and the picture of God they present can be just as much of a distortion as the one presented by Catholics.
