After the flood, Noah and his family gave thanks to the Lord with offerings as the Lord has saved them. God smelled the fragrance and was happy! He promised then to not destroy the earth with a flood again; He will see the rainbow and remember the covenant He made with us.
God gave us a sign through the parable of the fig tree. When the twigs get tender and its leaves appear, we know that summer is near. When we see revival in Israel, we know the day when the Lord is coming for us is near. This promise gives us great hope and endurance, knowing that all these will come to pass. Heaven and earth will pass away, but His words will never pass away – His promises never fail.
God gave Abraham and Sarah their promised child in their old age. This reminds me of my own story, where my father (whose Christian name is Abraham too) and mother waited almost ten years to receive God’s gift of a child (me!) to them. We are Abraham’s seed and heirs according to God’s promise in the Bible.
