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.
It will be healing to your flesh and refreshment to your bones. - Proverbs 3:5-8
Trust in the Lord with all your heart - We must love, rely on, cling to, and adhere to Jesus with all that we are.
...do not lean on your own understanding - "There is not a greater enemy to the power of religion, and the fear of God in the heart, than conceitedness of our own wisdom." - Matthew Henry. We must go to God's word prayerfully and in humility, seeking the Lord through the guidance of the Holy Spirit.
In all your ways acknowledge him, - "And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength" (Mark 12:30). What is it that you are holding back? What is it that you are afraid to sacrifice for the Lord? It must be understood that whatever blocks or hinders us in our relationship and walk with Jesus Christ is not worth keeping and holding on to. Pray and go to the word seeking to believe and understand that what Christ gives us is so far beyond anything this world offers that it cannot even be compared.
and he will make straight your paths. - "The LORD is my chosen portion and my cup; you hold my lot. The lines have fallen for me in pleasant places; indeed, I have a beautiful inheritance. I bless the LORD who gives me counsel; in the night also my heart instructs me. I have set the LORD always before me; because he is at my right hand, I shall not be shaken. Therefore my heart is glad, and my whole being rejoices; my flesh also dwells secure. For you will not abandon my soul to Sheol, or let your holy one see corruption. You make known to me the path of life; in your presence there is fullness of joy; at your right hand are pleasures forevermore" (Psalm 16:5-11).
Be not wise in your own eyes - "But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong" (1 Corinthians 1:27). Be a humble child before the Father and he will bless you with the wisdom of His word.
fear the LORD, and turn away from evil. - Repent, turn away from the sin that has held you in bondage, and turn away from the lies of this world that have told you that it was within your power or the power of a false god of your own understanding to be freed from your sin. There is only one God and there is only one way to be freed from the sin that separates you from Him and that is through the saving sacrifice of Jesus Christ. "Jesus said to him, 'I am the way, and the truth, and the life. No one comes to the Father except through me'" ( John 14:6). "And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved" (Acts 4:12).
It will be healing to your flesh and refreshment to your bones. - "Whoever believes in me, as the Scripture has said, 'Out of his heart will flow rivers of living water'" ( John 7:38).
