Let me ask you only this: Did you receive the Spirit by works of the law or by hearing with faith? (Galatians 3:2 ESV)
The heart of man finds it difficult to believe that so great a treasure as the Holy Spirit is gotten by the mere hearing of faith. The hearer likes to reason like this: Forgiveness of sins, deliverance from death, the gift of the Holy Spirit, everlasting life are grand things. If you want to obtain these priceless benefits, you must engage in correspondingly great efforts. And the devil says, "Amen."
We must learn that forgiveness of sins, Christ, and the Holy Spirit, are freely granted unto us at the preaching of faith, in spite of our sinfulness. We are not to waste time thinking how unworthy we are of the blessings of God. We are to know that it pleased God freely to give us His unspeakable gifts. If He offers His gifts free of charge, why not take them? Why worry about our lack of worthiness? Why not accept gifts with joy and thanksgiving?
Right away foolish reason is once more offended. It scolds us. "When you say that a person can do nothing to obtain the grace of God, you foster carnal security. People become shiftless and will do no good at all. Better not preach this doctrine of faith. Rather urge the people to exert and to exercise themselves in good works, so that the Holy Spirit will feel like coming to them."
What did Jesus say to Martha when she was very "careful and troubled about many things" and could hardly stand to see her sister Mary sitting at the feet of Jesus, just listening? "Martha, Martha," Jesus said, "thou art careful and troubled about many things: but one thing is needful; and Mary hath chosen that good part, which shall not be taken away from her." A person becomes a Christian not by working, but by hearing. The first step to being a Christian is to hear the Gospel. When a person has accepted the Gospel, let him first give thanks unto God with a glad heart, and then let him get busy on the good works to strive for, works that really please God, and not man-made and self-chosen works.
