John 20:24-29 (AMP)
24 But Thomas, one of the Twelve, called the Twin, was not with them when Jesus came.
25 So the other disciples kept telling him, We have seen the Lord! But he said to them, Unless I see in His hands the marks made by the nails and put my finger into the nail prints, and put my hand into His side, I will never believe [it].
26 Eight days later His disciples were again in the house, and Thomas was with them. Jesus came, though they were behind closed doors, and stood among them and said, Peace to you!
27 Then He said to Thomas, Reach out your finger here, and see My hands; and put out your hand and place [it] in My side. Do not be faithless and incredulous, but [stop your unbelief and] believe!
28 Thomas answered Him, My Lord and my God!
29 Jesus said to him, Because you have seen Me, Thomas, do you now believe (trust, have faith)? Blessed and happy and to be envied are those who have never seen Me and yet have believed and adhered to and trusted and relied on Me.

A doubting Thomas is a sceptic who refuses to believe without direct personal experience—a reference to the Apostle Thomas, who refused to believe that the resurrected Jesus had appeared to the ten other apostles until he could see and feel the wounds received by Jesus on the cross. Hence the “believing to seeing.” Are you doubting Thomas?
There are so many doubting Thomases in the world, even among believers. We have all heard or probably said things like “seeing is believing,” “I will believe it when I see it,” “I can’t believe this,” “this/that is not possible.” Well, great news, because according to Matthew 19:26, all things are possible with God.
We have all acted like Thomas at some point or know someone like him; someone difficult to convince of anything without proof and doubts everything they hear.
Vs 25 “if I don’t see the mark of nails in His hands, put my finger into the mark of nails and put my hand into His side, I will never believe.” This was Thomas’ response to being told that they’d seen the Lord.
How about you? What is your reaction to something the Lord has or is doing around you? Are you one of those whose motto is seeing is believing?
Unbelievers can exercise their unbelief because that’s what they are; “unbelievers.” Unbelief is a huge issue in the lives of many believers.
The Christian walk is one of FAITH and the only means by which we enter God’s will for us but how can you enter His will if you don’t believe in who He is, what He’s done and how He loves you.
We all struggle with doubts sometimes, but we must overcome them as quick as we can Psalm 94:19.
Believing that God is all good; and that he is ever ready to impart to his creatures whatever they need but only if there is no doubt, that is they don’t weaver in faith, having no doubt concerning the truth of the grand and fundamental principles of God, and that, when we ask sincerely and fervently without hesitating, we receive so much good from God. James 1:6.
We miss out on a lot of blessings and favour from the Lord when we chose to see His mighty power at work before believing in His faithfulness. Our need to see before believing is offensive to the Father because it shows how much we doubt His love and grace.
Doubt offends God. Psalm 95:9-11.
Doubt closes doors of blessings.
Doubt stops your prayers from being answered.
Doubt causes stagnation.
Doubt closes the door to healing, favour and miracle.
Don’t allow doubts and unbelief to stop you from enjoying all that Christ died to give you. You didn’t need a sign to accept Christ as your saviour, don’t ask for one to prove that He can and will do what He says He will.
Christ is asking and encouraging you to believe in Him without physical evidence but to believe in faith to see His glory.
Learn to ask the Father to grant you the grace to believe without physical evidence in Jesus name.
Shalom
