God Doesn't Give Us What We Can Handle.

Hebrews 12:12 "Therefore strengthen the hands which hang down, and the feeble knees, 13 and make straight paths for your feet, so that what is lame may not be dislocated, but rather be healed"

That their affliction may be endured with patience, which is the main drift of the apostle's discourse on this subject and he again returns to exhort them that for the reason before mentioned they should lift up the hands that hang down and the feeble knees, Hebrews 12:12. A burden of affliction is apt to make the Christian's hands hang down, and his knees grow feeble, to dispirit him and discourage him but this he must strive against, and that for two reasons:-- First, That he may the better run his spiritual race and course. Faith, and patience, and holy courage and resolution, will make him walk more steadily, keep a straighter path, prevent wavering and wandering. Secondly, That he may encourage and not dispirit others that are in the same way with him. There are many that are in the way to heaven who yet walk but weakly and lamely in it. Such are apt to discourage one another, and hinder one another but it is their duty to take courage, and act by faith, and so help one another forward in the way to heaven. That their affliction may be improved to a greater degree of holiness. Since this is God's design, it ought to be the design and concern of his children. - Matthew Henry
