Obedience and Prayer

“There are many Christians to-day who are doing things that are not pleasing to God, and leaving undone things which would be pleasing to God. When you speak to them about these things they will confront you at once with the question, "Is there any command in the Bible not to do this thing?" And if you cannot show them some verse in which the matter in question is plainly forbidden, they think they are under no obligation whatever to give it up; but a true child of God does not demand a specific command. If we make it our study to find out and to do the things which are pleasing to God, He will make His study to do the things which are pleasing to us. Here again we find the explanation of much unanswered prayer: We are not making it the study of our lives to know what would please our Father, and so our prayers are not answered.

Take as an illustration of questions that are constantly coming up, the matter of theater going, dancing and the use of tobacco. Many who are indulging in these things will ask you triumphantly if you speak against them, "Does the Bible say, 'Thou shalt not go to the theater'?" "Does the Bible say,'Thou shalt not dance'?" "Does the Bible say,'Thou shalt not smoke'?" That is not the question. The question is, Is our heavenly Father well pleased when He sees one of His children in the theater, at the dance, or smoking? That is a question for each to decide for himself, prayerfully, seeking light from the Holy Spirit. "Where is the harm in these things?" many ask. It is aside from our purpose to go into the general question, but beyond a doubt there is this great harm in many a case; they rob our prayers of power.”
