Hebrews 8:10 “… I will put My laws in their mind and write them on their hearts…”
Many of us have been taught that we cannot trust our hearts.
We quote verses like "The heart is deceitful above all things, and desperately wicked…" (Jeremiah 17:9), not knowing that Jeremiah was referring to the man who had not received Jesus as his Lord and Savior.
I have had people come to me and say, "I don't know what I should do with my life."
"What is in your heart?" I'll ask them.
"I would love to work with children."… "Then work among children!"
"But I am waiting on the Lord to tell me to do that."… "Well, He has given you the desire, so go and work with children!"
"But the desire comes from my heart. How do I know if it is of God?"
Once you are saved, and you allow the seed of God's Word to become established in your new heart (Ezekiel 36:26), you can trust the promptings of your heart because God dwells in you and He leads you from within. Don't worry because His promptings will never contradict His Word. It will lead you to good success.
I remember years ago when I approached one of our youth ministry leaders and told him, "I think that you are called to be a full-time pastor." It turned out to be a confirmation of what he already knew on the inside. You see, God was already leading him from within. Today, he is pastoring a church with hundreds of people. I said to another, you are going to be a successful professional sportsman - and that's exactly what he became because it was his heart's desire!
If you enjoy something and desire to do it, then go for it! Go with the flow. God, Himself says that He will guide us from within. Don't doubt Him. And don't worry about the outcome. Your part is just to follow the flow. God's part is to work in you both the willingness and the performance of it! (Philippians 2:13)
