Are you a parent? How do you judge whether you kid is good? Do you expect perfection? Neither does God, and we are God's children (adopted) as a result of Baptism. We are under a different system - the system of Grace, not the Law. Under the Law, men try to earn their way to heaven by attempting to perfectly fulfill the law. Under the system of Grace, God views us as children. If we please Him with faith and good deeds, He will judge us as righteous (which is not from ourselves but relies on our cooperation with His grace).
I agree that we are the children of God.
Do you posit a time when you shall cast any of your children away from you ... because they have not pleased you ?
Would you expect that God will be any less merciful to His children ?John 6:37 All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out.
And do you posit that God forces us into heaven? Reconsider the Prodigal Son in Luke 15. Did the Father kick the son out, or did the son leave?
"Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord." Rom 8:39.
ONLY WE can keep ourselves out of heaven. ONLY WE can lose our inheritance - just like a child can disinherit himself from his parents.
Consider this. God loves even those who are in hell. Unfortunately, those people chose not to come into union with Him.
God desires all men to be saved - but some won't be because of their freedom to reject God.
