It is GOD Who changes the hearts of men. There will be times He'd cross our paths with people who are difficult to handle in order for us to learn how to love the way He does.
The GOD Who holds the entire universe in His hands, the One who owns everything, is the same One Who wants your heart - to make you experience the only perfect thing there is: His love.
Every trial is an opportunity for us to have the right mindset so that we may respond appropriately. The LORD is after our character and our struggles serve as His training ground.
