Since you call on a Father who judges each man’s work impartially, live your lives as strangers here in reverent fear. For [he’s giving us the reason now], you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way...
I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. And I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws. Ezekiel 36:26-27 (NIV)
It would be very easy to think of the mind, heart, and will as separate departments of your life that operate independently. But when we talk about the mind, the heart, and the will, we’re talking about your inner life viewed from different angles.
The Bible uses the words “heart” and “mind” in different ways, and it is not always easy to tell them apart. When we talk about God changing the mind, the heart, and the will, we are talking about one miracle, not three separate ones. It’s like a diamond with different facets.
The mind, the heart, and the will are one as the Father, the Son, and the Spirit are one. They may be distinguished but never separated. They may fulfill different functions, but they never act independently of one another.
A person’s mind, heart, and will are always in the same spiritual condition. When Christ brings light to the mind, he brings life to the heart, and strength to the will. He does these things together. That’s what makes the Christian life possible.
If your mind has been regenerated, your heart and your will have been regenerated too. God deals with you as a person. He saves all of you, not just a part of you. There is no such thing as a person who has been half regenerated.
Try to imagine what it would be like if God gave light to the mind, life to the heart, and strength to the will at different times.
