Dear saints, I trust that the Lord had been blessing and protecting you. One of the major hindrances to believing the Lord is our intellect. As rational and logical beings we want to reason everything out. That which we can't reason or explain, we will not believe or accept. As much as much as the Lord wants us to love Him with all of our mind (Matthew 22:37), the carnal mind of the unregenerate or semi-regenerate man will not accept the gospel and Christ (Romans 8:7) because it just doesn't make any sense to believe that someone can rise from the dead. It's only natural for such such people to ask for signs and wonders, just like Moses (Exodus 4), before they believe the Lord. Unfortunately, God is not obligated to convince such people and the only sign that the Lord will give them is the sign of Jonah.
Let's look at Luke 11:29-32. The Pharisees and the crowds were demanding a sign that Jesus was indeed the Messiah. They were not only testing Him (Matthew 16:1) but they also needed proof that Jesus was indeed the Son of God. The important thing for all of us to learn is that God is not obligated to prove Himself to anyone. Even when Moses inquired about the Lord, God merely stated His name as "I am" (Exodus 3:14). God had not existed, will not exist but is always existing. Our fallen natures may demand signs and wonders as proof, but the only proof that God has to provide is that he always existed and will do so long after time ends (Daniel 7:9-10, Revelation 1:8).
Let's consider Jesus the Son of Man. Although He is completely God, Jesus is also completely man. Christ never insulted or disbelieved God the Father as most of us do and never demanded any signs or wonders. Even on the rare occasions He asked God the Father for a sign (John 12:28), He did so to convince the unbelieving crowd (John 12:30) and not for His sake. It would have been natural for Jesus the Man to have doubts about God, but He demonstrated a life of flawless faith by never doubting God (John 11:42).
Are we asking God for signs, wonders and miracles today? As much as the Lord is still performing miracles, He is not obligated to convince us. The only sign God will offer us is the resurrection of Christ and the witness thereof (Luke 24:36-49; John 20-21). May we not put the Lord to a foolish test today. Amen.
