We can all struggle with doubt at times. The Bible gives encouragement and help. Also, pray for those who doubt to have a renewed faith.
Show mercy toward those who have doubts (Jude 1:22)
Why am I so sad?
Why am I so troubled?
I will put my hope in God,
and once again I will praise him,
my savior and my God.
So we are even more confident of the message proclaimed by the prophets. You will do well to pay attention to it, because it is like a lamp shining in a dark place until the Day dawns and the light of the morning star shines in your hearts. (2 Peter 1:19)
You have taught many people
and given strength to feeble hands.
When someone stumbled, weak and tired,
your words encouraged him to stand.
Don’t you know? Haven’t you heard?
The Lord is the everlasting God;
he created all the world.
He never grows tired or weary.
No one understands his thoughts.
He strengthens those who are weak and tired.
The father at once cried out, “I do have faith, but not enough. Help me have more!” (Mark 9:24)
Remember, I will be with you and protect you wherever you go, and I will bring you back to this land. I will not leave you until I have done all that I have promised you. (Genesis 28:15)
At once Jesus reached out and grabbed hold of him and said, “What little faith you have! Why did you doubt?” They both got into the boat, and the wind died down. Then the disciples in the boat worshiped Jesus. “Truly you are the Son of God!” they exclaimed. (Matthew 14:31-33)
I am writing this to you so that you may know that you have eternal life—you that believe in the Son of God. (1 John 5:13)
A week later the disciples were together again indoors, and Thomas was with them. The doors were locked, but Jesus came and stood among them and said, “Peace be with you.” Then he said to Thomas, “Put your finger here, and look at my hands; then reach out your hand and put it in my side. Stop your doubting, and believe!” Thomas answered him, “My Lord and my God!” Jesus said to him, “Do you believe because you see me? How happy are those who believe without seeing me!” (John 20:26-29)
