Understand this: Jesus doesn't invite you to follow Him because you believe in Him, He invites you to follow Him because He believes in you! He does not see you as you are but He sees you as what He can make you if you obey and follow His Word.
In Matthew 4:19 He said, "Follow Me and I will make you."
He knows what you can become when His grace touches your life.
2 Cor 3:18 But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord.
Matthew was a Jew and yet he collected taxes for the Romans, who had enslaved his people. In the people's eyes he was lower than low. Yet when Jesus called him, he became an Apostle and wrote the first book in the New Testament.
When Jesus called Phillip and Nathanael to discipleship, as recorded in the first chapter of John, beginning in vs. 43 The following day Jesus wanted to go to Galilee, and He found Philip and said to him, “Follow Me.”
44 Now Philip was from Bethsaida, the city of Andrew and Peter.
45 Philip found Nathanael and said to him, “We have found Him of whom Moses in the law, and also the prophets, wrote—Jesus of Nazareth, the son of Joseph.”
46 And Nathanael said to him, “Can anything good come out of Nazareth?” Philip said to him, “Come and see.”
47 Jesus saw Nathanael coming toward Him, and said of him, “Behold, an Israelite indeed, in whom there is no deceit!”
48 Nathanael said to Him, “How do You know me?” Jesus answered and said to him, “Before Philip called you, when you were under the fig tree, I saw you.”
49 Nathanael answered and said to Him, “Rabbi, You are the Son of God! You are the King of Israel!”
50 Jesus answered and said to him, “Because I said to you, ‘I saw you under the fig tree.’
Nathanael's scepticism was understandable; at that time Nazareth was an obscure little hill town, remote and of no consequence. It was not sophisticated or glamorous -quite the opposite. It was not a place that anyone expected the Messiah to come from. Despite his scepticism, Nathanael followed Philip to meet Jesus.
When Jesus saw Nathanael coming toward Him, He said, “Here truly is an Israelite in whom there is no deceit.” (verse 47). Nathanael accepted this description as true and wondered how Jesus knew his character, having never met him before. Jesus explained, “I saw you while you were still under the fig tree before Philip called you” (verse 48).
Nathanael then immediately recognized Jesus as the Christ, calling him the 'Son of God' and the 'King of Israel'. (verse 49).
Even after three years of exposure to Jesus and His miracles and messages, many of the disciples still had doubts.
How often did Jesus say to them things like, "You of little faith… why do you not believe?… If only you believed you would see."
Jesus knew they were anxious about what would happen when He left them and went back to Heaven, so He said in John 14:16-17 "And I will pray the Father, and He will give you another Helper, that He may abide with you forever— 17 the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you."
The Greek word for comforter is parakletos and that means 'one who comes alongside to help.'
Just remember there will never be a day when you don't need God's help!
So Jesus simply says "Come as you are, come and I will change you. You've tried your way and it didn't work, now try My way!"
Come follow Him and you won't be disappointed!
