Ether 12:6 Those that keep commandments, receive a testimony of them. Those that don't keep the commandments, do not.

 Ether 12:6  “Sometimes we try to do it backward. For example, we may take this approach: I will be happy to live the law of tithing, but first I need to know that it’s true. Maybe we even pray to gain a testimony of the law of tithing and hope the Lord will bless us with that testimony before we have ever filled out a tithing slip. It just doesn’t work that way. The Lord expects us to exercise faith. We have to consistently pay a full and honest tithe in order to gain a testimony of tithing. This same pattern applies to all the principles of the gospel, whether it is the law of chastity, the principle of modesty, the Word of Wisdom, or the law of the fast” (Bonnie L. Oscarson, “Be Ye Converted,” Ensign or Liahona, Nov. 2013, 77).

Elder Maxwell. Receiving blessings is like opening a vault of heaven. 3rd tumbler falls only when what is sought is right for us.

 

"Petitioning in prayer has taught me that the vault of heaven, with all its blessings, is to be opened only by a combination lock: one tumbler falls when there is faith, a second when there is personal righteousness, and the third, and final tumbler falls only when what is sought is (in God's judgment, not ours) 'right' for us.

"Sometimes we pound on the vault door for something we want very much, in faith, in reasonable righteousness, and wonder why the door does not open. We would be very spoiled children if that vault door opened any more easily than it does now.

"I can tell, looking back, that God truly loves me by the petitions that, in his perfect wisdom and love, he has refused to grant me. Our rejected petitions tell us not only much about ourselves, but also much about our flawless Father."
