Love is our goal, right? Peter gives us a very clear map to being able to show such unselfish love as described in this passage. For me, showing love isn't always that easy or convenient. But when we go down Peter's list and do what he suggests, it is possible.
Our loving and merciful heavenly Father hates sin, not just because it is an offense to Him, but because in His wisdom He knows it can hurt or destroy us, who are the very objects of His love.
