First, I want to remind you that in the last days there will come scoffers who will do every wrong they can think of and laugh at the truth. This will be their line of argument: “So Jesus promised to come back, did He? Then where is He? He’ll never come! Why, as far back as anyone can remember, everything has remained exactly as it was since the first day of creation.”
II Peter 3:3-4 (TLB)
Dearly loved friends, don’t always believe everything you hear just because someone says it is a message from God: test it first to see if it really is. For there are many false teachers around, and the way to find out if their message is from The Holy Spirit is to ask: Does it really agree that Jesus Christ, God’s Son, actually became man with a human body? If so, then the message is from God. If not, the message is not from God but from one who is against Christ, like the “antichrist” you have heard about who is going to come, and his attitude of enmity against Christ is already abroad in the world.
I John 4:1-3 (TLB)
