John 1:12-13 ESV But to all who did receive Him, who believed in His name, He gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
1 John 3:1a ESV See what kind of love the Father has given to us, that we should be called children of God; and so we are.

And be assured that from here on, no matter where life takes you, your position is secure:
Romans 8:38 NKJV For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord.
