The writer to the Hebrews says we must ". . . strive diligently to enter into the rest . . ."
After the verses about rest, we are reminded of the power of the Word, and then shown that we have a high priest who intercedes for us.
So why is there so little rest? How many can say, "Yes, I am tasting the Sabbath Rest of Hebrews 4."
Resting in the Lord is a discipline and means turning a deaf ear to the insistent voices that press us to feel responsible to bear everything. Resting in the Lord means going to Him and putting the burden down, using deliberately formed communication. Resting in the Lord means focusing the thoughts on His Word instead of letting the mind gnaw on the situation.
Resting in the Lord means not talking about what might happen, what should happen, what could have happened, or what did happen. It means agreeing with God and doing the next thing as unto the Lord.
Soldier of The Cross, give it to Him. Perhaps over and over.
Then, look up and move on.
