WAGE THE WAR!!!
Don't just start it, continue to pursue to FIGHT for what is Yours in Christ Jesus. Life, as a believer, is a battle... I've been reading and meditating on the book of Joshua: Take your possession/portion/blessing to which Christ has already paid for on the cross and pursue to destroy the sin in you and preserve the things that pertains to faith that is in you. We are not wrestling with flesh and blood guys, 'but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places (Ephesians 6:12).'
Have faith in God, the fight isn't your but His!
