Yes but not always will it be a miracle or a wonderous event. Sometimes people have a deeply ingrained desire for alcohol and inspite of what they know and have lost and the many headaches and hangovers and through the lack of food they go back to it, over and over, time and time again.
Matthew 21:44 And whosoever shall fall on this
stone shall be broken: but on whomsoever it shall
fall, it will grind him to powder.
Jesus christ is that stone.
When temptation comes our way, if we earnestly desire to overcome that tempting, we pray, get on our knees and pray about everything we can think of, pray to god that the inclination to sin go away. Spend 3 minutes -
40 hrs, whatever it takes.. but through prayer we can be strengthened by christ to not sin. If we do not desire change in ourselves and our lives, chances are we will not pray and we will end up sinning.
We need to fall on the rock for strength and salvation.
