Here are a few verses for thought:
But to all who did receive Him, who believed in His name, He gave the right to become children of God.
Romans 8:14-16-For all who are led by the Spirit of God are sons of God. For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry,“Abba! Father!” The Spirit Himself bears witness with our spirit that we are children of God.
But when the fullness of time had come, God sent forth His Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons. And because you are sons, God has sent the Spirit of His Son into our hearts, crying, “Abba! Father!”
Religion that is pure and undefiled before God, the Father, is this: to visit orphans and widows in their affliction, and to keep oneself unstained from the world.
“Whoever receives one such child in My name receives Me."
And not for the nation only, but also to gather into one the children of God who are scattered abroad.
1 John 3:1-2-
See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know Him. Beloved, we are God's children now, and what we will be has not yet appeared; but we know that when He appears we shall be like Him, because we shall see Him as He is.
For His Glory,
