Paying tithing always pays off ! How it pays off is quite a different story. There is often a lag time between obedience and blessing because the Lord wants to give us enough time to make sure we know that we are trying to change. Sometimes the lag time is short because we need the reinforcement of receiving the blessing. Two different things we need to accomplish. Start changing our lives in his direction, and changing our lives enough that we can see that we have achieved a commandment. We are blessed for trying to change, and we are blessed for changing. We need both sorts of blessings. We are LDS not because we are like him, but because we want to be like him.
