Do not reckon that God will give you a life without difficulty!
"Man is born to trouble as surely as sparks fly upward!" Job 5:7
"How frail is humanity! How short is life, how full of trouble!" Job 14:1
"My life is consumed by anguish and my years by groaning; my strength fails because of my affliction, and my bones grow weak." Psalm 31:10
"Many are the afflictions of the righteous" Psalm 34:19
David did not expect to pass through life without experiencing difficulties. He had many severe trials. He expected to have troubles, and he certainly was not disappointed. Nor will you be.
Do not reckon that God will give you a life without difficulty! Tell me, if you can, of any child of His who ever had such a portion? He had one Son without sin—but no son without sorrow. No, that Son who had no sin, was the Man of Sorrows and acquainted with grief. So you must expect the Lord to deal with you as He does with the rest of His household.
"Here on earth you will have many trials and sorrows." John 16:33
"God disciplines us for our good, that we may share in His holiness. No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it." Hebrews 12:10-11
