John 1:12 But as many as received Him, to them He gave the right to become children of God, to those who believe in His name:
By believing in the name of Jesus Christ as being the Son of God, by receiving Him as our Messiah, Saviour and Redeemer, we are filled with a glorious hope; but more than that we are given a wonderful inheritance.
We are given the inheritance of being called children of God, pardoned of our sins and sanctified by His blood.
Whilst it may be nice to think we obtain a physical inheritance from family, our spiritual inheritance is worth far more and endures for eternity rather than just a fleeting moment or two in physical life.
