God tells us through His word, the Bible, what we are to seek – Seek first His Kingdom and his righteousness (Matthew 6:33) and to seek God, his righteousness and meekness (Zephaniah 2:3). He also tells us through His word, the Bible, what we are NOT to seek.

In Numbers 15, the LORD commands Moses to tell his people that they are to make for themselves tassle like reminders to remind themselves of His commandments that they must do, not once but twice (vs 39 and vs 40) and sandwiched in between, He makes an interesting yet profound counsel – to seek not after their own heart or to seek not after their own eyes.

The Bible advises us to keep our heart with diligence (i.e., guard it) for out of it are the issues of life (Proverbs 4:23) and that the lust of the eyes is of the world and not of God (1 John 2:16). We should be loving the Lord our God with ALL our heart (and with all of our soul, our mind and our strength – Mark 12:30) and our eyes must be fixed on Jesus (looking unto Him) who is the author and finisher of our faith (Hebrews 12:2). In other words, in filling our heart with the love for God and in fixing our eyes on Jesus, the Son of God, we will be heeding to the LORD’s counsel, which is to seek not after our ‘own’ heart or after our ‘own’ eyes.

Numbers 15: 37-41 (KJV)
37
And the LORD spake unto Moses, saying,
38
Speak unto the children of Israel, and bid them that they make them fringes in the borders of their garments throughout their generations, and that they put upon the fringe of the borders a ribband of blue
39
And it shall be unto you for a fringe, that ye may look upon it, and remember all the commandments of the LORD, and do them ; and that ye seek not after your own heart and your own eyes, after which ye use to go a whoring:
40
That ye may remember, and do all my commandments, and be holy unto your God.
41
I am the LORD your God, which brought you out of the land of Egypt, to be your God: I am the LORD your God.
