We are at present children of God
BY FAITH.
26: For ye are all the children of God
by faith in Christ Jesus.
27: For as many of you as have been baptized into Christ have put on Christ.
Gal. 3:26
We have the down payment of the Spirit but actually we are not full Sons as yet.
13: In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
14: Which is the
earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
Eph. 1:13-14
We have the
SPIRIT OF ADOPTION.
Note the difference between the spirit of adoption and the
ADOPTION ITSELF.
15: For ye have not received the spirit of bondage again to fear; but ye have received the
Spirit of adoption, whereby we cry, Abba, Father.
Rom. 8:15
22: For we know that the whole creation groaneth and travaileth in pain together until now.
23: And not only they, but ourselves also, which have the
firstfruits of the Spirit, even we ourselves groan within ourselves,
waiting for the adoption, to wit, the redemption of our body.
24: For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for?
Rom. 8:22-24
So strictly speaking we are not yet Sons but will be made so at the resurrection.
WE ARE WAITING FOR THE ADOPTION.
This agrees with the teaching of Yeshua that we become Children of God at the resurrection.
35: But they which shall be accounted worthy to obtain that world, and the resurrection from the dead, neither marry, nor are given in marriage:
36: Neither can they die any more: for they are equal unto the angels;
and are the children of God, being the children of the resurrection. Luke 20:35-36
So in summary we are children of God in that we have received the Spirit as a downpayment of what is to come if we endure to the end.
At that time....the resurrection we receive the actual adoption as Sons are are Children of God in fact and not just by faith. peace and love
