When he (the Lord) shall appear, the saints will be like him; and if they are not holy, as he is holy, and perfect, as he is perfect, they cannot be like him; for no being can enjoy his glory without possessing his perfections and holiness, no more than they could reign in his kingdom without his power.”
(Lectures on Faith 7:10)
When He appears, you need to be like Him. Lay down the burden of guilt, lay down the burden of sin, stop focusing on that stuff, and become like Him. You become like Him by doing His works. And you do His works by serving other; by ministering to the needs of others. When you do that, it is a natural by-product of that process, ordained by laws established before the foundation of the world that light and truth will grow within you. You will have compassion when you minister to the needs of others with compassion. Your heart will open too and receive within it light and truth, when your conduct reflects the same conduct as a merciful, holy and just God, whom you claim to worship. Worship Him by imitating Him. Worship Him by doing His works. Worship Him by making a living sacrifice. Set aside the junk that occupies you and go do something that is holy for someone else. However mundane and trivial it may seem to you, when you relieve the suffering of other people something changes in you. You become different. You become better. You become more like our Lord, because when you give whatever it is you give away, you get more in return. But make sure that what you give goes to relieve the suffering of others.
I left engineering school in 2018 and have been working in healthcare ever since. Working in an industry where I am constantly helping to relieve the suffering of others has made me a much different person. Grateful to be a healthcare worker during these times- to be burdened and privileged to be part of a work that has broken and grown my heart.
