John 8:13-14

13So the Pharisees said to him, aYou are bearing witness about yourself; your testimony is not true.” 14Jesus answered, Even if I do bear witness about myself, bmy testimony is true, for I know cwhere I came from and dwhere I am going, but eyou do not know where I come from or where I am going.

1 John 5:10-11

10Whoever believes in the Son of God fhas the testimony in himself. Whoever does not believe God ghas made him a liar, hbecause he has not believed in the testimony that God has borne concerning his Son. 11And this is the testimony, that God gave us ieternal life, and jthis life is in his Son.
