(Psa 74:16 KJV) The day is thine, the night also is thine: thou hast prepared the light and the sun.
As Christians, we are not exempt from trouble, set backs, and disappointments. Sometimes the night is long and dark. Sometimes we cannot see God, cannot make sense of what is happening in life. You may not know where God is, but God knows where you are at. God is God in the good times; He is God in the bad. God is the God of the day, but God is also God of the night. The new day will dawn, but until that time, remember the night belongs to the Lord also. Trust Him.
