John 1:10-13 - suggested further reading: Galatians 3:26
We see in these verses the vast privileges of all who receive Christ and believe on Him. We are told that "As many as received Him, to them gave He power to become the sons of God, even to them that believe on His name."
Christ will never be without some servants. If the vast majority of the Jews did not receive Him as the Messiah, there were, at any rate, a few who did. To them He gave the privilege of being God's children. He adopted them as members of His Father's family. He reckoned them His own brethren and sisters, bone of His bone and flesh of His flesh. He conferred on them a dignity which was ample recompense for the cross which they had to carry for His sake. He made them sons and daughters of the Lord Almighty.
Privileges like these, be it remembered, are the possession of all, in every age, who receive Christ by faith and follow Him as their Saviour. They are "children of God by faith in Christ Jesus" (Galatians 3:26). They are born again by a new and heavenly birth and adopted into the family of the King of kings. Few in number, and despised by the world as they are, they are cared for with infinite love by a Father in heaven who, for His Son's sake, is well pleased with them. In time He provides them with everything that is for their good. In eternity He will give them a crown of glory that fadeth not away. These are great things! But faith in Christ gives men an ample title to them. Good masters care for their servants and Christ cares for His.
Are we ourselves sons and daughters of God? Have we been born again? Have we the marks which always accompany the new birth - sense of sin, faith in Jesus, love of others, righteous living, separation from the world? Let us never be content till we can give a satisfactory answer to these questions.
For Meditation: The idea of His being a child of God filled John with praise, anticipation and longings to be holy (1 John 3:1-3). What does it do for you?
