Thomas Manton gives four counsels to assist the weak in faith in being able to call God their Father.
First, “disclaim when you cannot apply.” If you cannot say “Father,” plead on your “fatherless” condition, using such texts as Hosea 14:3, “In thee the fatherless find mercy.”
Second, “own God in the humbling way.” Come to the Father like the prodigal son, confessing your unworthiness, or like Paul, as the chief of sinners. Come to Him as your Father-Creator if you cannot come to Him as your Father-Savior.
Third, “call him Father in wish.” If you cannot call Him Father with directness, do it with desire. “Let us pray ourselves into this relation, and groan after it, that we may have a clearer sense that God is our Father in Christ,” he counsels.
Fourth, make “use of Christ Jesus.” Since Christ’s name means so much in heaven, “if you cannot come to God as your Father, come to him as the God and Father of our Lord Jesus Christ (Eph. 3:14). Let Christ bring you into God’s presence. He is willing to change relations with us. Take him along with you in your arms. Go to God in Christ’s name: `Whatsoever you ask in my name, shall be given to you.’”
