Sins of Ommission...by Charles Finney

Now begin, and take up first what are commonly, but improperly, called Sins of Omission.
1. Ingratitude. Take this sin and write down under that heading all the times you can remember where you have received favors from God and others for which you have never expressed gratitude or thankfulness. How many cases can you remember? Some remarkable change of events, that saved you from ruin. Write down the instances of God's goodness to you when you were in sin, before your conversion, for which you have never been half thankful enough; and the numerous mercies you have received since. How long the list of instances, where your ingratitude has been so black that you are forced to hide your face in confusion! Go on your knees and confess them one by one to God, and ask forgiveness. The very act of confession, by the laws of suggestion, will bring up others to your memory. Put these down. Go over them three or four times in this way, and see what an astonishing number of mercies there are for which you have never thanked God.
2. Lack of love to God. Think how grieved and alarmed you would be if you discovered any lack of affection for you in your wife, husband, or children; if you saw another absorbing their hearts, and thoughts, and time. Perhaps in such a case you would nearly die with a just and virtuous jealousy. Now, God calls Himself a jealous God; and have you not given your heart to other loves and infinitely offended Him?
3. Neglect of the Bible. Put down the cases when for perhaps weeks, or longer, God's Word was not a pleasure. Some people, indeed, read over whole chapters in such a way that they could not tell what they had been reading. If so, no wonder that your life is spent at random, and that your religion is such a miserable failure.
4. Unbelief. Recall the instances in which you have virtually charged the God of truth with lying, by your unbelief of His express promises and declarations. God has promised to give the Holy Spirit to them that ask Him. Now, have you believed this? Have you expected Him to answer? Have you not virtually said in your hearts, when you prayed for the Holy Spirit: "I do not believe that I shall receive"? If you have not believed nor expected to receive the blessing which God has expressly promised, you have charged Him with lying.
5. Neglect of prayer. Think of the times when you have neglected secret prayer, family prayer, and prayer meetings; or have prayed in such a way as more grievously to offend God than to have omitted it altogether.
