It was only by faith in Christ that they could secure pardon of sin and receive strength to obey God's law. They must cease to rely upon their own efforts for salvation, they must trust wholly in the merits of the promised Saviour, if they would be accepted of God.
But when, through the open door of the cross and the name and power of Jesus Christ, I commend myself to the Father's heart, then God cancels all my past, accepts all my present, swears His holy name for my future and the love of God take me over. Then fear goes out of my heart, because love has come in.
