(Proverbs 2:1 KJV) My son, if thou wilt receive my words, and hide my commandments with thee;
It is easy to “receive” (3947). It is a bit more challenging to “hide” (treasure NASB) (6845). Think about last Christmas. Assume that you received a nice pile of gifts. When it was time to get them out of the living room, what did you do? If you are like most people the general pile was transferred to your bed or some other flat space. There it awaited its distribution, but there are always exceptions. If you received one very special item you either put it in a special place or gave it special attention. It is possible that there was another item, such as a package of Peeps, that fell down behind the bed and were forgotten about. You know which ones were treasured by the way in which they were treated.
Around the tree where you were receiving you made the appropriate comments. In your room the real attitude came out. It is the same with the wisdom of God. We learn to make the appropriate responses to the sermon. We say stirring things at the Bible study. But do we treasure?
So? Separate the things you hear and give them the fitting amount of attention. I am not sure we need to fixate on separating linen and wool but we might want to mediate a little on turning the other cheek.
