1 John 5:11-13 And this is the testimony: God has given us eternal life, and this life is in his Son. He who has the Son has life; he who does not have the Son does not have life. I write these things to you who beleive in the name of the Son of God so that you may know that you have eternal life.
Romans10: 9,10 That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth you confess and are saved.
