When we learn how to keep our heart like Jesus did, we begin to have a healthy cooperation between what we think, what we feel, what we habitually do, and how we relate to others. We can choose the thoughts that renew us over the thoughts that destroy us. We can engage with our emotions to understand the reason for those emotions. We can re-train our body away from the slavery of engrained, destructive habits. But our will alone can never change a person. We need our will to be empowered by the Spirit, through surrendering to God’s will.
