Charles Spurgeon reminds us that we must always be mindful of our surroundings:
She is the church militant here below, and both in suffering and in service she is made to prove that she is in an enemy’s country. She is contending for the truth against error, for the light against darkness: till the day break and the shadows flee away, she must maintain her sentinels and kindle her watch fires; for all around her there is cause to guard against the enemy, and to descend the royal treasure of gospel truth against its deadly foes.
–C. H. Spurgeon
