Let us labour therfore to enter into that rest, lest any man fall after the same example of unbelief.
Hebrews 4:11 (KJV)
Laboring to rest is to get to where our our mind, our will and our emotions rest confidently in the finished works of Jesus. We do not labor 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.
