Put on the whole armor of God, that you may be able to stand against the schemes of the devil.
Praying and sinning will never live together in the same heart. Prayer will consume sin, or sin will choke prayer. ― J.C. Ryle
One of the Fruit of the Spirit is peace — a gift which we receive from God. Yet here, in Ephesians, the focus of scripture turns to war. Timothy Keller, in a sermon on spiritual warfare, quotes the 19th century Anglican bishop of Liverpool J.C. Ryle on the way spiritual war and peace exist in the life of healthy followers of Christ:
There are thousands of men and women who go to chapels and churches every Sunday and call themselves Christians… But you never see any ‘fight’ about their religion! Of spiritual strife, and exertion, and conflict, and self-denial, and watching, and warring they know literally nothing at all.
Let us consider these propositions.… The saddest symptom about many so-called Christians is the utter absence of anything like conflict or fight. They eat, they drink, they dress, they work, they amuse themselves, they get money, they spend money, they go through a scanty round of formal religious services once or even twice a week, but the great spiritual warfare … its watchings and strugglings, its agonies and anxieties, its battles and contests … of all this they appear to know nothing at all.
All true saints are soldiers. A real Christian can be known as much by his inward warfare as by his inward peace.
