Men will rationalize everything and think that their views and choices are right. The Lord tells us that these men consider their way right - in their own eyes. The problem is that our greatest scrutiny is not that of our own eyes - but rather the Lord God who weighs our hearts.
God told Samuel, when he was looking at Jesse's sons, not to look at the outside appearance. Jesse was impressed with the size and the look of several of Jesse's sons - yet God was not looking for a well wrapped package - he was interested in the contents - the heart. God's instruction to Samuel that day was that man looks on the outside, but God looks on the heart. The saying goes, "You can fool some of the people some of the time, but you can't fool all of the people all of the time." There needs to be another phrase added to this saying. "You can't ever fool God." The Lord weighs what is going on in our hearts. The pharisee may look awfully good standing on the street corner praying out loud - but God sees the pride and selfishness of his heart. The giver may make an offering at the temple which sounds and looks impressive to men - but the widow with her two pennies is the one with the most heart in the matter. Oh, how we need to fundamentally distrust what we think is right in our own eyes. It is too easy to be deceived in this matter. Wait for the Lord - search His Word - know His heart and you will find the true measure of any man and any situation.
The Word warns us to wait for God's judgment. We are to wait until God weighs in on all things. He is not affected by greed or injustice - He cannot be bought off with bribes or wrongly influenced by flattery - He cannot be misled or deceived. His statements are true statements - and they arise from One who has absolute omniscience - thus we know He does truly know everything. Wait for God's evauation in the end - when every man will receive His praise from God. Until then - trust what the Scriptures say on all matters for a true picture of His mind and what brings joy to His heart. Search them daily and live according to what you find there. That way you will not be deceived into the false evaluation of your own heart - but you will be looking to the One who is right in His estimation of all things.
