Here's a quote from what I read today, regarding repentance.
The usual biblical word describing the no we say to the world's lies and the yes we say to God's truth is repentance. It is always and everywhere the first word in the Christian life. John the Baptist's preaching was, 'Repent, for the kingdom of heaven is at hand' (Mt. 3:2). Jesus' first preaching was the same: 'Repent, for the kingdom of heaven is at hand' (Mt 4:17). Peter concluded his first sermon with 'Repent, and be baptized' (Acts 2:38). In the last book of the Bible the message to the seventh church is 'be zealous and repent' (Rev 3:19).
Repentance is not an emotion. It is not feeling sorry for your sins. It is a decision. It is deciding that you have been wrong in supposing that you could manage your own life and be your own god; it is deciding that you wee wrong in thinking that you had, or could get, the strength, education and training to make it on your own; it is deciding that you have been told a pack of lies about yourself and your neighbours and your world. And it is deciding that God in Jesus Christ is telling you the truth. Repentance is a realization that what God wants from you and what you want from God are not going to be achieved by doing the same old things, thinking the same old thoughts. Repentance is a decision to follow Jesus Christ and become his pilgrim in the path of peace.
