God is loving and caring and wants the best for his children. His anger is manifested from time to time. It is during these times that we must be humble and recognize where our success comes from and obey all of God's commandments. Love God and you will feel his love in greater abundance.
“And in nothing doth man offend God, or against none is his wrath kindled, save those who confess not his hand in all things, and obey not his commandments.”
