The motive of the son towards the father is not fear, but love. And this love is produced by the fact that God, in love, provided this great, wonderful plan for men, "having in love predestinated us for adoption as sons through Jesus Christ to himself,"--Eph. 1:5, and the fact that the Saviour loved us and gave Himself for us (Gal. 2:20). Hence, Paul tells us, "The love of Christ [not the fear of the law, nor the fear of Hell] constrains us; because we thus judge, that if one died for all, then all died; and he died for all, that they who live should not henceforth live unto themselves, but unto him who died for them, and rose again." Our Saviour, the night before His crucifixion, made clear that this was to be the motive in the life of God's children. In instituting the Lord's supper He said, "This is my blood of the new covenant which is shed for many for the remission of sins."--Matt. 26:28; then, following this, before leaving the supper room, He said, "If ye love me, keep my commandments,"--John 14:15, not, "if ye are afraid of the law, keep my commandments"; not, "if ye are afraid of going to Hell, keep my commandments"; not, "if ye wish to make sure of going to Heaven, keep my commandments"; but, "if ye love me." But why love Him? Because "this is my blood of the new covenant which is shed for many for the remission of sins." That this love, and that _this kind of love_ is clearly the motive power of the real Christian life, notice the teaching of the Saviour in Luke 7:41, 43, "There was a certain creditor who had two debtors; the one owed five hundred pence and the other fifty. And when they had nothing to pay he frankly forgave them both. Tell me, therefore, which of them will love him most? Simon answered and said, I suppose that he to whom he forgave most. And he said unto him, Thou has rightly judged." This is no mere theory, that love _ought_ to be the controlling motive, but it _is_ the controlling motive. And it is not a mere theory that love _ought_ to constrain the real Christian, the real believer, but the love of Christ _does_ constrain us (2 Cor. 5:14).
