1 John 5:9-13

If we accept the testimony of men, how much more should we accept the more authoritative testimony of God that he has testified concerning his Son? Those who believe in the Son of God have the living testimony in their hearts. Those who don’t believe have made God out to be a liar by not believing the testimony God has confirmed about his Son. This is the true testimony: that God has given us eternal life, and this life has its source in his Son. Whoever has the Son has eternal life; whoever does not have the Son does not possess eternal life. I’ve written this letter to you who believe in the name of the Son of God so that you will be assured and know without a doubt that you have eternal life.
