Not many strive against flesh. That ye be not slothful, but followers of them who through faith and patience inherit the promises. A veil of flesh divides the spiritually hungry from the flesh-pleasers. Flesh pleasers will into break through the flesh. Strive through the wilderness to get fruits of Canaan.
Hope is fuel for striving.
He should have fought the fight of faith. Faith comes from the word. God SAID you shall die if you eat wrong fruit. Adam lost the birthright. When saints act ungodly, fight the fight of faith and let not go of the birthright.
