There was a preacher named “John the Baptist.” John wasn’t a Baptist preacher, he was just a simple preacher, who spoke of the coming of the church (kingdom) and the need for mankind to repent. He baptized his converts in the river Jordon, which is why he was known as the Baptist or immerser. Matt 3.1-6. John 1:19-33.
Now, back to his sermon title, “repent”. Since God and man are never on the same page someone would have to give. Isaiah 55:6-9. 1 Sam 16.7. And since God is greater than man, it sure wouldn’t be Him. Man is nothing like God and if man wants to see God in peace, man is going to have to make change in his life. There are things that man believes that he must quit believing. There are things that man thinks and he has to quit thinking those things. There are things which man does and he must quit doing those things. Man cannot give salvation, yet he wants it; so man is going to have to change his ways, if he expects to enter heaven and be with God. 1 Pt 1.13-16
Reader, if you don’t repent, change your ways and do what God expects of you, you are not His buddy, you are not right in His eyes. You must repent. Acts 17.30 Lk 13.3
