What does it really mean to sit? When we walk or stand, we bear on our legs all the heaviness and weight of our body, whereas when we sit down our entire weight rests upon the chair which we sit on. We grow weary when we walk or stand, but we feel rested and refreshed when we have sat down for a while. In walking or standing, we expend a great deal of energy but when we are seated we relax at once, because our weight no longer falls upon our muscles and our sinews, but upon something else outside of ourselves.
So too then in spiritual things, to sit down is simply to rest our whole weight upon another - to transfer the load of ourselves, our future, our everything - upon the Lord Jesus. We let Him bear the responsibility for every burdening thing and thereby we cease to carry it ourselves! Mat.11:28 "Come to me, all you who are weary and heavy burdened, and I will give you rest for your souls"
God has made us all to be seated in Christ Jesus and if we are seated in Him correctly, then He is the one that is doing all of the work of our living. He takes care for all of the bearing of our heaviness, all of the cause of our weariness, all of the fear, worry and anxiety! We can truly cast all of our burdens and ourselves upon someone that can do that much for us. Jesus has the power, given to Him by God, to care for each one of us to that extent! 1 Peter 5:7 "Cast all your anxiety on Him because He cares for you"
Today in the real Church as the body of Christ, are we really permitting this to happen in our Christian life experience? Are we allowing the Lord Jesus to care for us, or are we still trying to do His job for Him by caring for ourselves? If we are cast upon Him, then all the power of worry and anxiety has ceased, and we are dynamically relaxed in all that we do! We have in fact sat down in Him.
