For Christianity begins not with a big DO, but with a big DONE. Thus Ephesians opens with the statement that God has "blessed us with every spiritual blessing in the heavenly places in Christ" (1:3) and we are invited at the very outset to sit down and enjoy what God has done for us; not to set out to try and attain it for ourselves....

What does it really mean to sit down? When we walk or stand we bear on our legs all the weight of our own body, but when we sit down our entire weight rests upon the chair or couch on which we sit...In walking and standing we expend a great deal of energy, but when we are seated we relax at once, because the strain no longer falls upon our muscles and nerves but upon something outside of ourselves. So also in the spiritual realm, to sit down is simply to rest our whole weight--our load, ourselves, our future, everything--upon the Lord.

Watchman Nee. SIT, WALK, STAND.
