"...embark in the service of God, see that ye serve him with all your heart, might, mind and strength, that ye may stand blameless before God at the last day..." (Doctrine and Covenants Section 4:2)

"...with joyfulness, and with gladness of heart..." (Old Testament Deuteronomy 28:47)

He will -

"...the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live..." (Old Testament Deuteronomy 30:6)
