In Golf, most golfers know how rare it is to get a hole in one. The lucrative eagle on a par 3 hole is much sought after. The average golfer has odds of 12,500 to 1 of making a hole in one. So as you can see, the odds are stacked against you. but we do know that it does happen. Many pro have made holes in one. So there must be something that makes golfers more likely to get holes-in-one. Experience. Every time a golfer plays and practices and works on his accuracy, He grows more and more likely to make the hole in one.
Similarly in our lives we need to learn how to identify the prompting of the Spirit and to act upon them. It isn't easy to recognize the things that come from the Spirit verses our thoughts. in Moroni 7:13-17 we learn, "But behold, that which is of God inviteth and enticeth to do good continually; wherefore, every thing which inviteth and enticeth to do good, and to love God, and to serve him, is inspired of God. Wherefore, take heed, my beloved brethren, that ye do not judge that which is evil to be of God, or that which is good and of God to be of the devil. For behold, my brethren, it is given unto you to judge, that ye may know good from evil; and the way to judge is as plain, that ye may know with a perfect knowledge, as the daylight is from the dark night. For behold, the Spirit of Christ is given to every man, that he may know good from evil; wherefore, I show unto you the way to judge; for every thing which inviteth to do good, and to persuade to believe in Christ, is sent forth by the power and gift of Christ; wherefore ye may know with a perfect knowledge it is of God.
But whatsoever thing persuadeth men to do evil, and believe not in Christ, and deny him, and serve not God, then ye may know with a perfect knowledge it is of the devil; for after this manner doth the devil work, for he persuadeth no man to do good, no, not one; neither do his angels; neither do they who subject themselves unto him."
I testify that as we practice recognizing the promptings of the Holy ghost and acting on them we will be more likely to respond to a promptings. while promptings aren't as rare as holes-in-one, it is harder to take an opportunity to act on a prompting from the Spirit.
