“Trust in the Lord with all thine heart; and lean not unto thine own understanding.”

Proverbs 3:5 “Trust in the Lord with all thine heart; and lean not unto thine own understanding.”  

This is now the third time “heart” has been mentioned in this chapter. Head faith is not a saving faith, but a heart belief is, (Rom. 10:9-10), for it is a trust in the Lord; i.e., a dependence upon Him to save. “He guards against his recommendation of ‘good understanding’ in verse 4 being perverted into a ground for self-reliance,” [Faussett]. This is to be a total trust “with all thine heart.” Divided hearts are faulty in their faith toward God, (Hosea 10:2). Hence, David prayed for his heart to be united to fear the Lord, (Ps. 86:11-12). This, however, does not apply solely to salvation, for many heresies have been brought in because men tried to reason out doctrinal truth—leaning unto their own wisdom—instead of simply believing God’s Word in all that is says.

Proverbs 3:6

 “In all thy ways acknowledge him, and he shall direct thy paths.” “‘Acknowledge Him’ by referring all thy ways to His will, trusting in His power, wisdom, providence, goodness, righteousness, and feeling that without Him you can do nothing,” [Faussett]. Most of our failures are due to pride, for we think that our own wisdom, strength and piety are sufficient, and so we do not acknowledge Him as necessary in all things. We need the knowledge that Jeremiah had, (Jer. 9:23-24; 10:23.) We need God’s direction in everything, for this alone is a safe path to tread.

My overview,

"Trust in the Lord with all your heart and lean not to your own understanding. In all your ways acknowledge Him and He shall direct your paths. Do not be wise in your own eyes, fear the Lord and depart from evil. It will be health to your flesh and strength to your bones."

I love these verses because they not only promise me lots of good things like direction, health and strength, but He is teaching me to not depend on what I think. I don't need to know it all or be in control of everything! He knows what's best for me. What's best for me according to the Lord, is to TRUST and REST in Him. Jesus is our rest.
John 3:16 tells us that "God so loved the world that He gave His Only begotten Son that whoever believes in Him shall not perish, but have everlasting life."
When we put our faith and trust in God through faith in Jesus Christ we can have eternal life! Jesus is the One who took the punishment for all our sins on the Cross 2000 years ago, and was raised from the dead. When we put our faith and trust in what Jesus did for us and receive Him as our Lord and Savior, the Bible says, we are "born-again". We become a new person and all our sins are forgiven and we can now come into the presence of God without the sense of guilt and shame. We are now able to fellowship with the Lord daily!

God Bless to all
