One idea is embodied in these two sentences. According to a very common construction in the book of Psalms and in the book of Proverbs, and in other books of Holy Scripture, the latter sentence simply repeats the declaration of the former, in order to increase the emphasis and the force, for the "broken heart" is the same as the "contrite spirit," and the Lord being "nigh" is the same as the Lord "saveth."
I. Consider the broken heart and contrite spirit. The heart before us may be considered to be like a piece of fine mechanism disordered or some work of art fractured, or like flesh when worn and wasted and bruised and mangled. God is looking at the broken heart and crushed spirit, and as He looks at it He sees all the natural susceptibilities of sorrow awakened. The heart may be broken (1) by the consciousness and the remembrance of sin; (2) by fears and perplexities which are not explained simply by sin, and which are not explained by external circumstances; (3) by some tremendous outward affliction, like that of the widow or the widower. To such a heart God is nigh, and such a spirit God seeks to save.
II. Look at the position which God occupies in relation to the broken heart and crushed spirit. (1) He is nigh in knowledge. He knows the broken heart better than it knows itself. (2) He is nigh in ministration and salvation.
III. The doctrine of this passage instructs us (1) to check all morbid craving for creature help and fellowship; (2) to avoid thinking, feeling, and acting as though God were a distant help; (3) to remember that the resources of God are available in the hour of greatest need. (4) Guided by this passage, do not let feelings of despondency and despair creep into your spirit and take possession of it. (5) A broken heart and crushed spirit are named as not uncommon things. (6) God's being nigh is mentioned as something ordinary also.
