Led to Enter His Rest

Isaiah 63:14  
As a beast goes down into the valley, And the Spirit of the Lord causes him to rest, So You lead Your people, To make Yourself a glorious name.

Hebrews 4:1, 9-11   1 Therefore, since a promise remains of entering His rest, let us fear lest any of you seem to have come short of it.  9 There remains therefore a rest for the people of God. 10 For he who has entered His rest has himself also ceased from his works as God did from His.  11 Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience.

God gives animals rest when they are tired; how much more does He lead us in rest from our efforts to earn deliverance from our sin?  His grace paid the debt we owed the righteous Judge once and for all.  So if we do not choose to enter that rest, doing God's work as He guides and tells us to do, then we come short (the definition do sin) again.  So we need to obey by entering the rest in Christ and His work for us, not attempting to earn what we cannot.
