In our text, one might be troubled by the pitiful bunch Christ invites to come to Him. These are pictured as working for something they have not yet achieved, and overwhelmed with that which they cannot find relief. There is no satisfaction nor contentment here.
Now one might expect Christ to invite world leaders, deep thinkers, problem solvers, the successful or the famous into His kingdom. Just think how they might advance the cause of Christ! To the contrary, I Cor. 1:18-31 tells us that Christ's tool chest has non of the worlds wisdom and sufficiency in it.
Christ invites those who see their need of Him. As the song writer says, "All the fitness He requireth is to see your need of Him" One never trusts Christ without a need, nor does he repent apart from a view of his hopeless state without forgiveness.
All who truly come to the Savior are poor and needy sinners, heavy laden with sin, guilt, doubt, fears and the cares of this life. In spite of all their labors, they can find no peace, but alas, they hear the sweetest words, "Come unto me,----and I will give you rest" They simply believe these words, trust Christ for their longings, and rest in His merit. They are no longer restless, no longer pitiful.
