We need to understand that sin is at war with us and Jesus is calling us to take an aggressive attitude toward it. He's not saying we should literally mutilate ourselves if we sin, but to get on the front lines and do whatever it takes to win these daily battles with temptation, which are uniquely different for every person. If internet pornography is a temptation for you - and it is for at least 94- of American men who admit to having looked at porn within the last 6 months - if porn is a problem for you, put a filter on your computer and phone, confess your sin and get accountable to someone. If drunkenness is a problem for you, stay away from alcohol and the people who entice you to drink it. If it's pride, envy, self-righteousness, anger, unforgiveness, disobedience to parents, out of control lust, greed - whatever your particular temptation is, we need to get serious about it because sin's singular objective is our eternal ruin in hell.
