The temptation to abandon the healthy habits you are learning can be quite strong at times especially
over the WEEKEND! Your BEST chance to overcome beyond your own willpower is to follow the model of Jesus! He responded with scripture (Matthew 4:1-11) Memorizing and using scripture to battle your temptations is the ULTIMATE weapon! My favorite for temptation is 1 Corinthians 10:13 and I use it ALOT to overcome!
"No temptation can seize you, except that which is common to man, GOD is faithful, he will not let you be tempted beyond what you can bear, but when you are tempted he will offer you a way out so you can OVERCOME!"
