Don't waste your pain; use it to help others.
Don't worry about what you don't have if you do have faith!
God wants us to practice on Earth what we're going to do forever in eternity.
The only reason you can love God or anybody else is because God first loved you. And he showed that love by sending Jesus Christ to Earth to die for you.
Becoming like Christ is a long, slow process of growth.
We always get into trouble when we doubt God's love, because when we don't trust him, we don't obey him.
