The difficulties we face originate from one of three sources. Some are sent to us by the Lord to test our faith, others are the result of Satan's attacks, and still others are due to our own sinful choices.
God's arrows of affliction are sharp and painful so He can get our attention. He won't let His beloved children get away with sin because He knows it robs us of blessings, opportunities, and even character refinement.
Thank the Lord for using each person as a tool in your life to deepen your insight into His grace and conforming you to the image of His Son.
An unschooled man who knows how to meditate upon the Lord has learned far more than the man with the highest education who does not know how to meditate.
