God tells us that whoever believes in Him and confesses that belief can be saved. 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.
Jesus bought our salvation when He died on the cross. Salvation is not dependent on our efforts. We can't undo our salvation or do anything to hinder God's love for you, because His love never ends.
Following Jesus is about taking your next step. Salvation happens immediately, but following Jesus is a lifelong journey. Jesus has given you a new life, and our new selves are revealed over time. God isn't surprised when you mess up. He knows you will, and that's why He's saved you! God has given us His Spirit to walk with us and guide us as we take our next steps.
"'I and the Father are one.' Again the Jews picked up stones to stone Him, but Jesus said to them, 'I have shown you many great miracles from the Father. For which of these do you stone me?' 'We are not stoning you for any of these,' replied the Jews, 'but for blasphemy, because you, a mere man, claim to be God.'"
"Philip said, 'Lord, show us the Father and that will be enough for us.' Jesus answered: 'Don't you know me, Philip, even after I have been among you such a long time? Anyone who has seen me has seen the Father. How can you say, 'Show us the Father'?'"
"For I have come down from heaven not to do my will but to do the will of Him who sent me."
"I came from the Father and entered the world; now I am leaving the world and going back to the Father."
"Can any of you prove me guilty of sin? If I am telling the truth, why don't you believe me?"
"When Jesus saw their faith, He said to the paralytic, 'Son, your sins are forgiven.'"
"Then Jesus said to her, 'Your sins are forgiven.' The other guests began to say among themselves, 'Who is this who even forgives sins?'"
"Jesus answered, 'I am the way and the truth and the life. No one comes to the Father except through me.'"
"Jesus said to her, "I am the resurrection and the life. He who believes in me will live, even though he dies.'"
"Then those who were in the boat worshipped Him Jesus, saying, 'Truly you are the Son of God.'"
"Then the man said, 'Lord Jesus, I believe,' and he worshipped Him."
"Jesus went throughout Galilee, teaching in their synagogues, preaching the good news of the kingdom, and healing every disease and sickness among the people."
"Jesus rebuked the demon, and it came out of the boy, and he was healed from that moment."
"While Jesus was still speaking, someone came from the house of Jairus, the synagogue ruler. 'Your daughter is dead,' he said, 'Don't bother the teacher anymore.' Hearing this, Jesus said to Jairus, 'Don't be afraid; just believe, and she will be healed.' ...Meanwhile, all the people were wailing and mourning for her. 'Stop wailing,' Jesus said. 'She is not dead but asleep.' They laughed at Him, knowing that she was dead. But He took her by the hand and said, 'My child, get up!' Her spirit returned, and at once she stood up. Then Jesus told them to give her something to eat."
Luke 8:49-50, 52-55
"As He approached the town gate, a dead person was being carried out - the only son of his mother, and she was a widow. And a large crowd from the town was with her. When the Lord saw her, His heart went out to her and He said, 'Don't cry.' Then He went up and touched the coffin, and those carrying it stood still. He said, 'Young man, I say to you, get up!' The dead man sat up and began to talk, and Jesus gave him back to his mother."
"When He had said this, Jesus called in a loud voice, 'Lazarus, come out!' The dead man came out, his hands and feet wrapped with strips of linen, and a cloth around his face. Jesus said to them, 'Take off the grave clothes and let him go.'"
"In their fright the women bowed down with their faces to the ground, but the men said to them, 'Why do you look for the living among the dead? He [Jesus] is not here; He is risen! Remember how He told you, while He was still with you in Galilee: 'The Son of Man must be delivered into the hands of sinful men, be crucified and on the third day be raised again.' Then they remembered His words."
