(12) Lust.--Rather, stubbornness, or perversity, from root meaning "to twist."

Verse 12. - So I gave them up unto their own hearts' lust. God's Spirit will not always strive with men (Genesis 6:3). After a time, if they persist in evil courses and disobedience to his commands, he "gives them up," withdraws from them, leaves them to themselves, to the "lust," or rather "stubbornness" of their own hearts - to their own perverse wills and imaginations. And they walked in their own counsels (comp. Jeremiah 7:24). This result is inevitable. If God no longer guides their thoughts and enlightens their understandings, they can but follow their own foolish counsels, and the result cannot but be disastrous.

81:8-16 We cannot look for too little from the creature, nor too much from the Creator. We may have enough from God, if we pray for it in faith. All the wickedness of the world is owing to man's wilfulness. People are not religious, because they will not be so. God is not the Author of their sin, he leaves them to the lusts of their own hearts, and the counsels of their own heads; if they do not well, the blame must be upon themselves. The Lord is unwilling that any should perish. What enemies sinners are to themselves! It is sin that makes our troubles long, and our salvation slow. Upon the same conditions of faith and obedience, do Christians hold those spiritual and eternal good things, which the pleasant fields and fertile hills of Canaan showed forth. Christ is the Bread of life; he is the Rock of salvation, and his promises are as honey to pious minds. But those who reject him as their Lord and Master, must also lose him as their Saviour and their reward.So I gave them up unto their own hearts' lust,.... Sometimes God gave them up, when they sinned, into the hands of the Moabites, or Ammonites, or Philistines, or other neighbouring nations, for their chastisement; but to be delivered up unto their own hearts' lust is worse than that; nay, than to be delivered to Satan: salvation may be the consequence of that, but damnation of this; and yet it is a righteous judgment; for as men like not to retain God in their knowledge, it is but just with him to give them up to vile affections, to a reprobate mind, to do things not convenient, Romans 1:24 there is nothing men are more desirous of than to have their hearts' lusts; and there is no greater judgment can befall them than to be left to the power of them, which must unavoidably issue in their ruin here and hereafter: and they walked in their own counsels; which were bad; after the imagination of their own evil hearts, and not after the counsels and directions of God in his word, and by his servants.
