It's true that grace is free but it's certainly not cheap. It's going to cost us everything.Jesus said (Matthew 6:24 NIV) “No one can serve two masters. Either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve both God and Money."So I either choose God or some other "god."I'm only saved through the blood of Jesus and that is something none of us can ever earn. But if I lay down everything to Him, then I'm free. Free to serve Jesus, free to love Him. Free to not have an agenda to lift up myself.Free to do only what Jesus tells me to do and when He says to do it.I'm not free to supplant him with some other "god" because His presence will be gone.Here's some quotes from Bonhoeffer's classic on the Cost of Discipleship.Let the Christian rest content with his worldliness and with this renunciation of any higher standard than the world. He is living for the sake of the world rather than for the sake of grace. Let him be comforted and rest assured in his possession of this grace - for grace alone does everything. Instead of following Christ, let the Christian enjoy the consolations of his grace! That is what we mean by cheap grace, the grace which amounts to the justification of sin without the justification of the repentant sinner who departs from sin and from whom sins departs. Cheap grace is not the kind of forgiveness of sin which frees us from the toils of sin. Cheap grace is the grace we bestow on ourselves. Cheap grace is the preaching of forgiveness without requiring repentance, baptism without church discipline, Communion without confession, absolution without personal confession. Cheap grace is grace without discipleship, grace without the cross, grace without Jesus Christ, living and incarnate. Costly grace is the treasure hidden in the field; for the sake of it a man will gladly go and sell all that he has. It is the pearl of great price to buy which the merchant will sell all his goods. It is the kingly rule of Christ, for whose sake a man will pluck out the eye which causes him to stumble, it is the call of Jesus Christ at which the disciple leaves his nets and follows him. Costly grace is the gospel which must be sought again and again, the gift which must the asked for, the door at which a man must knock. Such grace is costly because it calls us to follow, and it is grace because it calls us to follow Jesus Christ. It is costly because it costs a man his life, and it is grace because it gives a man the only true life. It is costly because it condemns sin, and grace because it justifies the sinner. Above all, it is costly because it cost God the life of his Son: “ye were bought at a price, and what has cost God much cannot be cheap for us. Above all, it is grace because God did not reckon his Son too dear a price to pay for our life, but delivered him up for us. Costly grace is the Incarnation of God.
