Acts 4:33 And with great power gave the apostles witness of the resurrection of the Lord Jesus: and great grace was upon them all.
According to church history, the apostle Thomas, died in Calamina, a city in the East Indies. While there, Thomas had put a stop to the idolatry that was running rampant in the land. The idolatrous priest was not happy about this at all and accused him before their king. The king sentenced Thomas to death -- first to be tormented by red hot plates and then cast into a glowing furnace and burned. When the priest saw that the fire was not hurting him, he pierced Thomas' side with spears and javelins, and finally Thomas died.
What turned the disciple who had fled Messiah during his trial and crucifixion, into a powerful saint of God? What turned turned his fears and doubt into powerful faith that was able to persevere through torture and fire? He had seen the Lord resurrected from the dead! He had witnessed His resurrection power!
Would you die for a lie? Of course not! Neither did the Apostles. Eleven of the twelve apostles suffered similar fates as Thomas.
The same power which rose Yeshua (Jesus) from the dead also gave Thomas and the other disciples the faith to endure --- and that same power is available to us!
However your faith is being tried today, know that God has given you the power to overcome every doubt, every fear, and every attack of the enemy!
