I John 5:18-21

Three Persevering Affirmations:


One of the assuring doctrines of the Christian faith is the fact that we are kept by the persevering grace of God. He is the keeper of our souls and life. Psalm 121:5 “The Lord is your keeper.” John Calvin rightly states, “for were any one of us the keeper of his own salvation, it would be a miserable protection.” It is the intercessory prayer of Christ to His Father on our behalf that keeps us forever more. John 17:11 “Holy Father keep them in Thy name, the name which Thou hast given Me, that they may be one, even as we are.”
