God recognizes the difference in the character of people, and God can distinguish between the sincere seeker and the belligerent scoffer. I think Thomas, the apostle of Jesus, is another example of the same type of character as Gideon. He needed more assurance of Jesus’ resurrection than just the word of his fellow disciples. Jesus provided that assurance because Thomas, though skeptical at first, sincerely wanted to know the truth (John 20:24-28).
A multitude of assurances are provided in God’s Word in order that the faithful of our day might be blessed as “those who have not seen and yet have believed” (v. 29).
Gideon was a person who needed great assurance. You may be that person who needs great assurance of truth. It's not a problem — God provides assurance aplenty to make complete the faith and hope of every believer who seeks him.
Whether you are an Isaiah who says, “Here am I; send me!” or a Gideon who says, “How can I save Israel?”, let your mind dwell on his word as you seek his strength.
Drink from the abundant fountain of confidence that nourished the faithful heroes of old. If you love God and his truth, God will assure your heart, and work in you “both to will and to do for His good pleasure” (Phil. 2:13).
