Running from sin means that we recognize sin “As the enemy,” and we instantly go the opposite way.
#1 With a tempting thought think, “This is the enemy.”
#2 Have a plan for new thoughts in advance. The Bible says to pursue “Righteousness, faith, love and peace.” This passage gives us 4 prayers:
“Father, that thought is the enemy. Help me to pursue righteousness.”
“Father, that thought is the enemy. Help me to pursue faith.”
“Father, that thought is the enemy. Help me to pursue love.”
“Father, that thought is the enemy. Help me to pursue peace.”
Running from sin is a great habit, and it goes to war with bad habits.
Finally, consider finding a technique to use to make these prayers remembered, available, and ready for use. Doing that is running from sin.
