Matthew 4:17 KJV:  From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.

Consider the words, “at hand.” If we have a pencil at hand, we have a pencil near and in our reach. When Jesus came to us, He placed the Kingdom of Heaven in our reach. The Kingdom of Heaven was not only something near as in the future, but near as in “Stretch out thy hand.” As a man seemed to grasp what Jesus was teaching, Jesus told him, "You are not far from the kingdom of God" (Mark 12:34).
As children of God, we belong to the Kingdom of Heaven. We are part of His glorious and eternal Kingdom. We need not wait to enjoy the riches of our relationship with God. He is near--even within our reach.
