Is it wrong for a Christian to have doubts?

¹⁶Meanwhile, the eleven disciples went to Galilee, to the mountain Jesus had designated. ¹⁷When they saw Him, they worshiped Him, but some doubted. ¹⁸Then Jesus came to them and said, “All authority in heaven and on earth has been given to Me. ¹⁹Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, ²⁰and teaching them to obey all that I have commanded you. And surely I am with you always, even to the end of the age.”

²⁰So they brought him, and seeing Jesus, the spirit immediately threw the boy into a convulsion. He fell to the ground and rolled around, foaming at the mouth. ²¹Jesus asked the boy’s father, “How long has this been with him?” “From childhood,” he said. ²²“It often throws him into the fire or into the water, trying to kill him. But if You can do anything, have compassion on us and help us.” ²³“If You can?” echoed Jesus. “All things are possible to him who believes!” ²⁴Immediately the boy’s father cried out, “I do believe; help my unbelief!” ²⁵When Jesus saw that a crowd had come running, He rebuked the unclean spirit. “You deaf and mute spirit,” He said, “I command you to come out and never enter him again.” ²⁶After shrieking and convulsing him violently, the spirit came out. The boy became like a corpse, so that many said, “He is dead.” ²⁷But Jesus took him by the hand and helped him to his feet, and he stood up.

²Meanwhile John heard in prison about the works of Christ, and he sent his disciples ³to ask Him, “Are You the One who was to come, or should we look for someone else?” ⁴Jesus replied, “Go back and report to John what you hear and see: ⁵The blind receive sight, the lame walk, the lepers are cleansed, the deaf hear, the dead are raised, and the good news is preached to the poor. ⁶Blessed is the one who does not fall away on account of Me. ”

²⁴Now Thomas called Didymus, one of the Twelve, was not with the disciples when Jesus came. ²⁵So the other disciples told him, “We have seen the Lord!” But he replied, “Unless I see the nail marks in His hands, and put my finger where the nails have been, and put my hand into His side, I will never believe.” ²⁶Eight days later, His disciples were once again inside with the doors locked, and Thomas was with them. Jesus came and stood among them and said, “Peace be with you.” ²⁷Then Jesus said to Thomas, “Put your finger here and look at My hands. Reach out your hand and put it into My side. Stop doubting and believe.” ²⁸Thomas replied, “My Lord and my God!” ²⁹Jesus said to him, “Because you have seen Me, you have believed; blessed are those who have not seen and yet have believed.”

²²And indeed, have mercy on those who doubt;

¹Surely God is good to Israel, to those who are pure in heart. ²But as for me, my feet had almost stumbled; my steps had nearly slipped. ³For I envied the arrogant when I saw the prosperity of the wicked. ⁴They have no struggle in their death; their bodies are well-fed. ⁵They are free of the burdens others carry; they are not afflicted like other men. ⁶Therefore pride is their necklace; a garment of violence covers them. ⁷From their prosperity proceeds iniquity; the imaginations of their hearts run wild. ⁸They mock and speak with malice; with arrogance they threaten oppression. ⁹They set their mouths against the heavens, and their tongues strut across the earth. ¹⁰So their people return to this place and drink up waters in abundance. ¹¹The wicked say, “How can God know? Does the Most High have knowledge?” ¹²Behold, these are the wicked— always carefree as they increase their wealth. ¹³Surely in vain I have kept my heart pure; in innocence I have washed my hands. ¹⁴For I am afflicted all day long and punished every morning. ¹⁵If I had said, “I will speak this way,” then I would have betrayed Your children. ¹⁶When I tried to understand all this, it was troublesome in my sight ¹⁷until I entered God’s sanctuary; then I discerned their end. ¹⁸Surely You set them on slick ground; You cast them down into ruin. ¹⁹How suddenly they are laid waste, completely swept away by terrors! ²⁰Like one waking from a dream, so You, O Lord, awaken and despise their form. ²¹When my heart was grieved and I was pierced within, ²²I was senseless and ignorant; I was a brute beast before You. ²³Yet I am always with You; You hold my right hand. ²⁴You guide me with Your counsel, and later receive me in glory. ²⁵Whom have I in heaven but You? And on earth I desire no one besides You. ²⁶My flesh and my heart may fail, but God is the strength of my heart and my portion forever. ²⁷Those far from You will surely perish; You destroy all who are unfaithful to You. ²⁸But as for me, it is good to draw near to God. I have made the Lord GOD my refuge, that I may proclaim all Your works.

⁵Now if any of you lacks wisdom, he should ask God, who gives generously to all without finding fault, and it will be given to him. ⁶But he must ask in faith, without doubting, because he who doubts is like a wave of the sea, blown and tossed by the wind. ⁷That man should not expect to receive anything from the Lord. ⁸He is a double-minded man, unstable in all his ways.

¹⁵But in your hearts sanctify Christ as Lord. Always be prepared to give a defense to everyone who asks you the reason for the hope that is in you. But respond with gentleness and respect,
