Jesus was addressing Thomas and his doubting, and then believing. He appeared to the disciples after he was resurrected, actually walking through closed doors twice. That will get your attention. His disciple became labeled as ‘doubting Thomas’, even today. And doubt is the major tool that Satan uses against both believers and non-believers. It started in the Garden. “Did God really say?”
In a fallen world with so many things bombarding us daily, we are prone to doubt, question, be insecure, even depressed. This is what the enemy wants, especially for those who have trusted Christ for their salvation. But look at the words that Jesus said to Thomas and the disciples. For those who have not seen Jesus personally, put our fingers in his wounds, and yet believe that he is the Son of God, you are blessed.
Apostle John, who knew Jesus intimately, and received profound revelation at the end of his life, wrote that it’s all about making sure we know. “Now Jesus did many other signs in the presence of the disciples, which are not written in this book; but these are written so that you may believe that Jesus is the Christ, the son of God, and that by believing you may have life in his name.” vss. 30,31
And John reemphasizes the purpose of his writings and all other scriptures. “I write these things to you who believe in the name of the Son of God, that you may know that you have eternal life.” John 5.13 The Spirit wants you to believe, Satan wants you to doubt. Your choice!
