What can lead to spiritual healing in the heart according to the Bible?

According to Scripture, true spiritual healing occurs through the grace of God and the obedience of faith. In Mark 3, when Jesus commanded the man to stretch forth his hand, he was demonstrating that through God's grace, the impossible becomes possible. The gospel is a command to believe on the Lord Jesus Christ, and with that command comes the enabling power of God. It is through this divine empowerment that a sinner can respond in faith, leading to renewed and transformed hearts. Grace is the mechanism by which God draws His chosen people to Himself, effecting healing and wholeness where there was once only brokenness.
