Your union with Christ, 2.Your justification by God's grace, and 3. Your regeneration by the Holy Spirit. All three divine Persons are intimately involved in your salvation. The Father justifies, the Son unites, and the Holy Spirit regenerates. What the Father starts, the Son continues, and the Holy Spirit insures.
Good works are the result and visible evidence of salvation.
They are not the ground of salvation. No, not at all. It's true that all of us fall short of God's ideal. It is also true that God's children sometimes fall into grievous sin. Those who do face the chastisement of their Heavenly Father.
