Jonathan Dodson has some helpful thoughts on repentance at his blog. He notes that there are three key things that must happen when we repent: confession, mortification (this means putting to death), and faith. He then gives a question for each to help you in the fight. For confession, we ask, “What do I want most?” For mortification we ask, “What lie am I believing when I do X?” For faith we ask, “What promises are opposite the lies I believe?”
From my example in the previous post of my own sin I would answer them this way.
1. I wanted money and financial security most.
2. I was believing the lie that God would not meet my needs and the lie that money would take care of me.
3. Two of the promises I needed to believe (and eventually did believe again) are that God will supply all my need according to his riches in glory in Christ Jesus (Philippians 4:19) and that God works all things for good for those who are called according to his purpose (Romans 8:28 – even finanicial difficutly).
