You’ve heard it and I’ve heard it; “Follow your heart” whenever there’s a decision to be made. I trusted my heart and wound up in some situations that were hard to get out of. I found out that I shouldn’t have followed and trusted my heart in making decisions about relationships and financial moves.
“The heart is deceitful above all things, And desperately wicked; Who can know it? I, the Lord, search the heart, I test the mind, Even to give every man according to his ways, According to the fruit of his doings. – Isaiah 17:9-10
This passage in Isaiah explains why we shouldn’t trust our heart. God declares the heart is deceitful and wicked. This is the state of our heart before letting the Holy Spirit dwell there to keep us from the desires and whims that not only hinder us in the natural realm but the spiritual realm as well. Trusting our heart rather than trusting God can lead to bondage and living beneath our privileges.
Then the question is asked in the passage; “Who can know it?” We will never know ourselves the way God knows us. So if we don’t know our hearts, why should we follow it?
God tests our heart and mind. King David declares God knows our thoughts from far away (Psalm 139:2). So it is best to seek God in everything we do, through prayer. He answers and instructs during prayer, which is a two-way communication with Him. It is always good to trust God, not your heart.
