What Does "Reconcile" Mean In The KJB?
Colossians 1:20 And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.

This word, "reconcile", was a joy to study into and make a video on. While preaching I often quote 2 Corinthians 5:18-19.

2 Corinthians 5:18 And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation;
2 Corinthians 5:19 To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation.

There was a point where I did not understand the word "reconcile". I had not studied into scripture much at that point in my new life in Christ. This is the reason I started doing this video series, so I can understand the words I am reading with more spiritual understanding. Doing this video series has given me joy and peace knowing more about the love my Lord and Saviour Jesus Christ had for me when he died for my sins, was buried, and rose again the third day according to the scriptures. He did all that while I was yet a sinner, he reconciled me to himself by Jesus Christ.

The King James Bible English is plain and simple. God is not willing that any should perish, he will have all men to be saved. So why would he keep the gospel in darkness and hard to understand words? The English is plain, it can be understood if you truly believe God and receive the King James Bible to be the word of God.

John 3:35 The Father loveth the Son, and hath given all things into his hand.
John 3:36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.
