John 3:27-36 John answered and said, “A man can receive nothing unless it has been given to him from heaven. 28 You yourselves bear me witness, that I said, ‘I am not the Christ,’ but, ‘I have been sent before Him.’ 29 He who has the bride is the bridegroom; but the friend of the bridegroom, who stands and hears him, rejoices greatly because of the bridegroom’s voice. Therefore this joy of mine is fulfilled. 30 He must increase, but I must decrease. 31 He who comes from above is above all; he who is of the earth is earthly and speaks of the earth. He who comes from heaven is above all. 32 And what He has seen and heard, that He testifies; and no one receives His testimony. 33 He who has received His testimony has certified that God is true. 34 For He whom God has sent speaks the words of God, for God does not give the Spirit by measure. 35 The Father loves the Son, and has given all things into His hand. 36 He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him.”

Colossians 1:15-18 He is the image of the invisible God, the firstborn over all creation. 16 For by Him all things were created that are in heaven and that are on earth, visible and invisible, whether thrones or dominions or principalities or powers. All things were created through Him and for Him. 17 And He is before all things, and in Him all things consist. 18 And He is the head of the body, the church, who is the beginning, the firstborn from the dead, that in all things He may have the preeminence.

2 Timothy 3:16-17 All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, 17 that the man of God may be complete, thoroughly equipped for every good work.

1 John 5:10 He who believes in the Son of God has the witness in himself; he who does not believe God has made Him a liar, because he has not believed the testimony that God has given of His Son.
