"An abomination to the Lord"...that is what my translation says a person with a perverse (or crooked; evil) heart is. (vs 20). It goes on to say that the blameless are His delight. Will I ever be blameless? Will I ever delight God? As long as we are sincere, as long as we are trying...we are a delight to God. Isn't that a wonderful thought to begin your day and encourage you to try hard to walk the right path?
Verse 21 continues this thought. Do you want your children, and their children to be blessed? Of course you do! I don't know of a woman who doesn't want that for her children. Of course, they will have troubles of their own...but in due time, they will be blessed as God promises.
Yes, today's verses were certainly an encouragement to me to do what is right all day long. At the end of the day I will search my heart. Did I delight God today? Will my actions of today be a blessing to my children?
