2 Timothy 4:2
Ephesians 2:19-23
Colossians 1:18
Ephesians 5:23-33
Paul said we need to preach the word because Jesus told us to preach the word. That is The Great Commission.
You have to believ in the word of God to share the word with others as God commanded us to do.
We stand on the KJV. We do this because it's the closest translation that we got. We got to believe that the word of God is what we stand on. There's power in the word of God. Actions speak louder than words and we need to show what we believe. We need to show that our focus is on Jesus.
I can prove that this is Jesus' church through the Bible. There's a lot of versions of the Bible but you can only get what you need to hear from God through the KJV.
Whatever church you go to, make sure that Christ is the head of that church and the focus.
