“In the life of the body a man is sometimes sick, and unless he takes medicine, he will die. Even so in the spiritual life a man is sick on account of sin. For that reason he needs medicine so that he may be restored to health; and this grace is bestowed in the Sacrament of Penance.” — St. Thomas Aquinas
Personally, my internal “check engine” light goes off every week. This tells me to go into the shop and have my soul inspected by an expert mechanic (the Holy Spirit), acknowledge what has prevented my internal engine from running according to God’s plan (pride, impatience, etc…) and humbly ask the mechanic to put me back up to speed through absolution. Don’t ignore these check engine or other warning lights for too long, or your venial sins will soon become mortal, (as I recently learned by not changing my brakes in time). Confession is so helpful…take advantage of this amazing gift!!
