1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was with God in the beginning. 3 Through him all things were made; without him nothing was made that has been made. 4 In him was life, and that life was the light of all mankind. 5 The light shines in the darkness, and the darkness has not overcome it. 6 There was a man sent from God whose name was John. 7 He came as a witness to testify concerning that light, so that through him all might believe. 8 He himself was not the light; he came only as a witness to the light. 9 The true light that gives light to everyone was coming into the world. 10 He was in the world, and though the world was made through him, the world did not recognize him. 11 He came to that which was his own, but his own did not receive him. 12 Yet to all who did receive him, to those who believed in his name, he gave the right to become children of God— 13 children born not of natural descent, nor of human decision or a husband’s will, but born of God. 14 The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth.

9 If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. 10 For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved.

 John 11:25-27        New International Version

25 Jesus said to her, “I am the resurrection and the life. The one who believes in me will live, even though they die; 26 and whoever lives by believing in me will never die. Do you believe this?” 27 “Yes, Lord,” she replied, “I believe that you are the Messiah, the Son of God, who is to come into the world.”

15 The Son is the image of the invisible God, the firstborn over all creation. 16 For in him all things were created: things in heaven and on earth, visible and invisible, whether thrones or powers or rulers or authorities; all things have been created through him and for him. 17 He is before all things, and in him all things hold together. 18 And he is the head of the body, the church; he is the beginning and the firstborn from among the dead, so that in everything he might have the supremacy. 19 For God was pleased to have all his fullness dwell in him, 20 and through him to reconcile to himself all things, whether things on earth or things in heaven, by making peace through his blood, shed on the cross.

13 When Jesus came to the region of Caesarea Philippi, he asked his disciples, “Who do people say the Son of Man is?” 14 They replied, “Some say John the Baptist; others say Elijah; and still others, Jeremiah or one of the prophets.” 15 “But what about you?” he asked. “Who do you say I am?”

16 Simon Peter answered, “You are the Messiah, the Son of the living God.”

17 Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. 18 And I tell you that you are Peter, and on this rock I will build my church, and the gates of Hades will not overcome it. 19 I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.” 20 Then he ordered his disciples not to tell anyone that he was the Messiah. 21 From that time on Jesus began to explain to his disciples that he must go to Jerusalem and suffer many things at the hands of the elders, the chief priests and the teachers of the law, and that he must be killed and on the third day be raised to life. 22 Peter took him aside and began to rebuke him. “Never, Lord!” he said. “This shall never happen to you!” 23 Jesus turned and said to Peter, “Get behind me, Satan! You are a stumbling block to me; you do not have in mind the concerns of God, but merely human concerns.” 24 Then Jesus said to his disciples, “Whoever wants to be my disciple must deny themselves and take up their cross and follow me. 25 For whoever wants to save their life will lose it, but whoever loses their life for me will find it. 26 What good will it be for someone to gain the whole world, yet forfeit their soul? Or what can anyone give in exchange for their soul?

28 Thomas said to him, “My Lord and my God!” 29 Then Jesus told him, “Because you have seen me, you have believed; blessed are those who have not seen and yet have believed.” 30 Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. 31 But these are written that you may believe[a] that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name.
