Jeremiah 17:5 Thus saith the Lord, Cursed be the man that trusteth in man, and maketh flesh his arm and whose heart departeth from the Lord.
the Bible speaks of the arm of the flesh and the arm of the Lord. One is based on humans ideas and effort; the other is based on God's plan and power.
It is hard work to carry out the plans and schemes you yourself devise because you are operating in the flesh. But when God starts something, he carires it through to completion without any struggle on your part. GLORY T0 GOD!!!!
If you are facing struggles, it may be because you are taking matters into your own hands instead of being patient and waiting on the Lord to work things out according to His PERFECT WILL.
So stop struggling --- turn away from the arm of the flesh and learn to live victoriously according to God's divine plan and purpose for your life.
