“Trust in the Lord with all your heart and lean not on your own understanding; in all your ways submit to him, and he will make your paths straight.” – Proverbs‬ ‭3:5-6‬ ‭NIV‬‬ – http://bible.com/111/pro.3.5-6.niv

What does it mean to trust God with all ur heart ?

My emotions, feelings, dreams, expectations, passions, fulfillment. Commitment no matter what it takes.

My own understanding ?

What makes sense to me, how things work, how I was brought up. My worldly opinion vs what the Bible / God says.

All my ways submit to Him ?

As a father, son, husband, friend, worker, businessman, disciple, individual. God know what is best. Follow His rules rather than my comfort and my thinking.
