Psalms 18:26

Those that forsake the ways of the Lord, depart from their God. But though conscious to ourselves of many a false step, let there not be a wicked departure from our God. David kept his eye upon the rule of God's commands. Constant care to keep from that sin, whatever it be, which most easily besets us, proves that we are upright before God. Those who show mercy to others, even they need mercy. Those who are faithful to God, shall find him all that to them which he has promised to be. The words of the Lord are pure words, very sure to be depended on, and very sweet to be delighted in. Those who resist God, and walk contrary to him, shall find that he will walk contrary to them, Le 26:21-24. The gracious recompence of which David spoke, may generally be expected by those who act from right motives. Hence he speaks comfort to the humble, and terror to the proud; "Thou wilt bring down high looks." And he speaks encouragement to himself; "Thou wilt light my candle:" thou wilt revive and comfort my sorrowful spirit; thou wilt guide my way, that I may avoid the snares laid for me. Thou wilt light my candle to work by, and give me an opportunity of serving thee. Let those that walk in darkness, and labour under discouragements, take courage; God himself will be a Light to them.

"With the pure thou wilt shew thyself pure; and with the froward thou wilt shew thyself froward." The sinner's frowardness is sinful and rebellious, and the only sense in which the term can be applied to the Most Holy God is that of judicial opposition and sternness, in which the Judge of all the earth will act at cross-purposes with the offender, and let him see that all things are not to be made subservient to wicked whims and wilful fancies. Calvin very forcibly says, "This brutish and monstrous stupidity in men compels God to invent new modes of expression, and as it were to clothe himself with a different character." There is a similar sentence in Leviticus 26:21-24, where God says, "and if ye walk contrary unto (or perversely with) me, then I will also walk contrary unto (or perversely, or roughly, or at random with) you." As if he had said that their obstinacy and stubbornness would make him on his part forget his accustomed forbearance and gentleness, and cast himself recklessly or at random against them. We see then what the stubborn at length gain by their obduracy; it is this, that God hardens himself still more to break them in pieces, and if they are of stone, he causes them to feel that he has the hardness of iron." The Jewish tradition was that the manna tasted according to each man's mouth; certainly God shows himself to each individual according to his character.
