The Psalmist addresses all the people who wait for the Lord God. His motivation is devotional and relational. He touches upon two essential aspects of human control system: mind and heart. These two areas of our life play a foundational role in establishing a rich and satisfying relationship with the Lord Jesus Christ. King Solomon says, “ Trust in the LORD with all your heart, and do not lean on your own understanding.  In all your ways acknowledge him, and he will make straight your paths.  Be not wise in your own eyes; fear the LORD, and turn away from evil. …(Proverbs 3:5-7 ESV)
The prophet Jeremiah states, “ Thus says the LORD: “Let not the wise man boast in his wisdom, let not the mighty man boast in his might, let not the rich man boast in his riches, …(Jeremiah 9:23 ESV) When David was handing the charge to his son Solomon, he said, “ “And you, Solomon my son, know the God of your father and serve him with a whole heart and with a willing mind, for the LORD searches all hearts and understands every plan and thought. If you seek him, he will be found by you, but if you forsake him, he will cast you off forever. (1 Chronicles 28:9 ESV)
In all these three discourses, the godly men like Solomon, Jeremiah and David with their wholehearted sense and sensibilities have given importance to one thing in life: giving our heart and mind to the Lord Jesus Christ. If our thoughts, desires and understanding are not subject to the gospel of Christ, our behavioural patterns will not be conformed to the likeness of Christ; the inmost desires of our heart will be tempered with the worldly scholarship, and we finally end up with trusting our ways and means.
