JESUS CHRIST IS THE TRUE LIVING GOD.—–
1JOHN 5:20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, [even] in his Son Jesus Christ. This is the true God, and eternal life.
Mat 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth
Rev 1:8 I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
He gives eternal life.Jesus bore your sins,shed His blood for you died and rose again and lives for ever.Believe this in your heart,God will forgive your sins.
