'Abide' in the Bible

the children indeed being not yet born, or having done anything good or worthless (that the purpose of God according to election might abide, not of works, but of him that calls),

Behold then the goodness and severity of God: upon them who have fallen, severity; upon thee goodness of God, if thou shalt abide in goodness, since otherwise thou also wilt be cut away.

And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
