"The only sign I will give them is the sign of Jonah." Luke 11:29
Trying to test Jesus, the crowd asked Jesus for a miraculous sign from heaven, and Jesus replied that the only sign He would give them was the sign of the prophet Jonah. The sign of Jonah is the sign of repentance.
I was quite impressed with Angelina Jolie's movie "Unbroken". It is the true story of Louis Zamperini, an American prisoner of war, who survived horrible maltreatment at the hands of sadistic captors. During his 47 day ordeal at sea before he was captured by the Japanese, Louis vowed that if God would save them, he would devote his life to serving Him.
He forgot about this prayer, especially during his harrowing captivity, but remembered it when he and his wife joined a Billy Graham Crusade. After Louis accepted Jesus as his Lord and Savior, he suddenly had respite from years of having nightly nightmares about strangling the "Bird", his especially sadistic and violent torturer. "It was a miracle!" he said.
In 1950, he went to Japan, and embraced and forgave some of the guards from his prison camp. Some even became Christians. In 1998, he attempted to meet with the "Bird", but Mutsuhiro Watanabe refused to see him.
How sad that Watanabe could not see God's gracious sign of forgiveness and His calling His son to return to Him and repent! No matter how black our heart is, no matter what evil we have done, God is ready and willing to accept us if we repent. Are there any signs we are missing? Or perhaps we need to be God's sign to someone badly in need of God's healing presence?
