Matthew 11:1-6: Now it came to pass, when Jesus finished commanding His twelve disciples, that He departed from there to teach and to preach in their cities. And when John had heard in prison about the works of Christ, he sent two of his disciples and said to Him, “Are You the Coming One, or do we look for another?” Jesus answered and said to them, “Go and tell John the things which you hear and see: The blind see and the lame walk; the lepers are cleansed and the deaf hear; the dead are raised up and the poor have the gospel preached to them. And blessed is he who is not offended because of Me.”
Psalm 22:1-5:
My God, My God, why have You forsaken Me?
Why are You so far from helping Me,
And from the words of My groaning?
O My God, I cry in the daytime, but You do not hear;
And in the night season, and am not silent.
But You are holy,
Enthroned in the praises of Israel.
Our fathers trusted in You;
They trusted, and You delivered them.
They cried to You, and were delivered;
They trusted in You, and were not ashamed.
John 20:24-29: Now Thomas, called the Twin, one of the twelve, was not with them when Jesus came. The other disciples therefore said to him, “We have seen the Lord.” So he said to them, “Unless I see in His hands the print of the nails, and put my finger into the print of the nails, and put my hand into His side, I will not believe.” And after eight days His disciples were again inside, and Thomas with them. Jesus came, the doors being shut, and stood in the midst, and said, “Peace to you!” Then He said to Thomas, “Reach your finger here, and look at My hands; and reach your hand here, and put it into My side. Do not be unbelieving, but believing.” And Thomas answered and said to Him, “My Lord and my God!” Jesus said to him, “Thomas, because you have seen Me, you have believed. Blessed are those who have not seen and yet have believed.”
Jude 22: Be merciful to those who doubt
Mark 9:14-28: And when He came to the disciples, He saw a great multitude around them, and scribes disputing with them. Immediately, when they saw Him, all the people were greatly amazed, and running to Him, greeted Him. And He asked the scribes, “What are you discussing with them?” Then one of the crowd answered and said, “Teacher, I brought You my son, who has a mute spirit. And wherever it seizes him, it throws him down; he foams at the mouth, gnashes his teeth, and becomes rigid. So I spoke to Your disciples, that they should cast it out, but they could not.” He answered him and said, “O faithless generation, how long shall I be with you? How long shall I bear with you? Bring him to Me.” Then they brought him to Him. And when he saw Him, immediately the spirit convulsed him, and he fell on the ground and wallowed, foaming at the mouth. So He asked his father, “How long has this been happening to him?” And he said, “From childhood. And often he has thrown him both into the fire and into the water to destroy him. But if You can do anything, have compassion on us and help us.” Jesus said to him, “If you can believe, all things are possible to him who believes.” Immediately the father of the child cried out and said with tears, “Lord, I believe; help my unbelief!” When Jesus saw that the people came running together, He rebuked the unclean spirit, saying to it, “Deaf and dumb spirit, I command you, come out of him and enter him no more!” Then the spirit cried out, convulsed him greatly, and came out of him. And he became as one dead, so that many said, “He is dead.” But Jesus took him by the hand and lifted him up, and he arose. And when He had come into the house, His disciples asked Him privately, “Why could we not cast it out?”
Matthew 17:20: Assuredly, I say to you, if you have faith as a mustard seed, you will say to this mountain, “Move from here to there,” and it will move; and nothing will be impossible for you.
John 6: 66-69: From that time many of His disciples went back and walked with Him no more. Then Jesus said to the twelve, “Do you also want to go away?” But Simon Peter answered Him, “Lord, to whom shall we go? You have the words of eternal life. Also we have come to believe and know that You are the Christ, the Son of the living God.”
