Noah was a righteous man amongst the corrupted in his generations. During the flood, he was kept safe along with the animals in the ark, for he had found favour in God’s eyes. When the flood was over, God made a rainbow appear and promised Noah that He would not destroy the earth again.
Our faithful God has worked miracles to many who are diagnosed medically barren. This is evident in the Bible and even in my wife, who was told that she would have difficulty conceiving but is now a mother of three. Thus, we should willingly receive the hope of life in Jesus with open hearts and thanksgiving!
When Jesus spoke of this to the thief, he is referring to the same promise God gave to Abraham (Genesis 22:17-18) Not the kind of paradise that is found on earth but is found in heaven. His Words are hope for all of us sinners. Showing how merciful our God is in this specific event in the Bible is a reminder that despite our grievous sins, we only need to have a repentant heart to receive hope (believe the words of Jesus) and the promise of salvation. The good thief believed so he immediately received his reward. This is a picture of encouragement to all of us, a promise of Paradise.
