Let us labour therfore to enter into that rest, lest any man fall after the same example of unbelief.
Hebrews 4:11 (KJV)
Much of our walk with the Lord is about laboring to enter into rest. This is not speaking of a physical rest, but much rather of a resting of the soul. It is to get to the place where our our mind, our will and our emotions rest confidently in the finished works of Jesus. And so we do not labor in our soul to try and get victory, we labor to get to the place of truly believing that Jesus has already won us the victory. We fill our minds and hearts with the Word of God until God’s promises become so real to us that all unbelief is cast out, and we rest in confident assurance of seeing God’s goodness in our lives.
