Do you believe that every word that God speaks is a seed? What do you do with seeds, you plant them! Maybe you don't like what you have been harvesting. If you want a God crop, you have to plant God seeds in your heart. The way to Rest is to cease from trusting in your own works, planting your own seeds that comes from the world, and rest in what Jesus has freely provided by grace. Stop relating to Jesus by what you do and start trusting toally in what Jesus has already done. We can't do this without Trusting by faith every word that proceeds out of the mouth of God.
Laboring in the Word by sowing God's word in our heart is one of the greatest things we can do to enter the Rest of God. It's time to sow the Word of God in your heart!
