What are the components of biblical repentance? How does it differ from mere sorrow?

Curt Daniels explains in this video that repentance first involves a change of mind. We see it the seriousness of our sin from God’s view. Second, we mourn over our sin. Our heart is changed. Third, there is a turning around, an about-face.

Each aspect is important and based upon Scripture. Repentance is not simply a mere showing of guilt or sorrow for sin and then immediately returning to it. Rather, it is a change of mind, a change of action, a desire to follow the commands of God. 

Romans 6:1-2 (NKJV) – “What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it?” 

Theologically and biblically repentance includes first a change of mind, metanoia is a Greek word. We have a different opinion of it. We see it from God's point of view. Secondly, a change of heart. Bible says we mourn over it.

Truly sorry that we have committed sins against the holy God. Thirdly, perhaps most importantly, it means a turning around about faith. Some people do the first two, but not the third, but they are essential.
