C. A voluntary element (_fiducia, credere in Deum_),—trust in Christ as Lord and Savior; or, in other words—to distinguish its two aspects: (_a_) Surrender of the soul, as guilty and defiled, to Christ’s governance. _Mat. 11:28, 29_—“_Come unto me all ye that labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me_”; _John 8:12_—“_I am the light of the world: he that followeth me shall not walk in the darkness_”; _14:1_—“_Let not your heart be troubled: believe in God, believe also in me_”; _Acts 16:31_—“_Believe on the Lord Jesus, and thou shalt be saved._” Instances of the use of πιστεύω, in the sense of trustful committance or surrender, are: _John 2:24_—“_But Jesus did not trust himself unto them, for that he knew all men_”; _Rom. 3:2_—“_they were intrusted with the oracles of God_”; _Gal. 2:7_—“_when they saw that I had been intrusted with the gospel of the uncircumcision._” πίστις = “trustful self‐surrender to God” (Meyer). In this surrender of the soul to Christ’s governance we have the guarantee that the gospel salvation is not an unmoral trust which permits continuance in sin. Aside from the fact that saving faith is only the obverse side of true repentance, the very nature of faith, as submission to Christ, the embodied law of God and source of spiritual life, makes a life of obedience and virtue to be its natural and necessary result. Faith is not only a declaration of dependence, it is also a vow of allegiance. The sick man’s faith in his physician is shown not simply by trusting him, but by obeying him. Doing what the doctor says is the very proof of trust. No physician will long care for a patient who refuses to obey his orders. Faith is self‐surrender to the great Physician, and a leaving of our case in his hands. But it is also the taking of his prescriptions, and the active following of his directions.
