The issue of overcoming a bad (sinful) habit is inversely proportional to growing in holiness.
When we begin our journey, we are not very holy but are very sinful. Through the infusion of grace, prayer and commitment we begin to overcome our sinfulness, grow in holiness and move closer to God.
So long as we remain focused on God, on Holiness, on the journey toward the narrow gate - and - on killing off bad habits and sin, we will not sin gravely.
There will be times though when we slip up…When we lose our focus on Loving God and we sin - maybe even gravely.
This is a bad thing…
We know it is a bad thing …
We are in danger…
We know we are in danger…
We hurt God and ourselves…
We recognize that we hurt God and ourselves…
SO - - -
We pick ourselves up as fast as we can, turn to God in humble and abject repentance, begging His forgiveness and recommitting Love to Him and promise to “sin no more”.
…And, of course, we commit to getting to confession as soon as you can.
bmullins and Nigel, you guys have a nice exchange above.
Our growing in Holiness and overcoming our sinful nature I like to equate to things like dieting or training to run a marathon. Consider what goes into each of these things - starting from a “couch potato” lifestyle. It takes hard work and commitment. It takes the help of others. Slipping up is expected, but at the same time hated. But one must remain focused on the goal and measure progress, not failures.
So long as one remains firmly and truthfully committed to the goal of Loving God with their whole heart, their whole mind and their whole strength…They will, by the grace of God, prevail…
Hope this helps
Peace
