O you who love the LORD, hate evil! He preserves the lives of his saints; he delivers them from the hand of the wicked. Light is sown for the righteous, and joy for the upright in heart.
When we love God, it is a necessary result that we also love what is right, for God is holy and righteous. And when we love what is right, we must hate what is wrong. We hate evil. We don't hate evil PEOPLE who are wrong, but rather the evil that is done. And when we do so, there are certain blessings that attend a love for God and what He is in all His holiness and goodness. That is displayed to us by God. We are blessed by loving God.
We are promised deliverance from the hand of the wicked. But...this promise has a dark warning in it. Wicked people oppose God and if we represent Him well, we will probably be opposed. But God will deliver us. We will face a struggle because good and evil are in opposition. But God will preserve the lives of His saints since He uses them for His good purposes. They cannot lose. Even in death, good will be known by God's graces.
God is doing something bigger than just any one life. I see that in the language of light being "sown". The seed is sown with the promise of future harvest. And loving God and hating evil work that way. Sometimes the promise is sown to be enjoyed in another season. It may not be immediate, but God will be glorified and His saints blessed by our worship of Him... our love and obedience to God right now will yield blessings. I trust that truth.
