The Windows Of Heaven, Elder David A. Bednar
The Lord has promised temporal and spiritual blessings for keeping the law of tithing; in addition, these blessings don’t always arrive in the way you crave. Why? Elder Bednar said, “we often receive significant but subtle blessings that are not always what we expect and easily can be overlooked.” For example he said you often want immediate financial deliverance, but the Lord might bless you with greater power to change your own circumstances instead of having them changed for you.
Spiritual blessings are much greater than temporal; therefore, changing your nature will bless you much more than receiving a large chunk of cash.
The Church of Jesus Christ of Latter Day Saints practices what it preaches, and it teaches this in two fundamental concepts.
