"Come unto me, all ye that labour and are heavy laden, and I will give you rest. Matthew 11:28"
As a child of God, God has given you the privilege to enjoy His rest. If you are not enjoying the rest of God, it simply means that you are still carrying your load instead of laying it on Jesus Christ of Nazareth.
How do you lay it on Jesus? You do so in prayer and afterwards refuse to think about the load, and rejoice in and celebrate Jesus Christ for taking up your load.
This is done in faith because we live by faith and not by sight, Romans 1:17. God has given every child of God natural gifts and spiritual gifts to profit withal.
Hence, if you are laboring, it means that you still have not discovered your gift or you have abandoned it. The will of GOD for us is to work from the place of rest where there is no struggle for what we do for the LORD.
Dearly beloved, think about this very gospel and stop laboring and carrying your load. Praise the LORD!
