This was given to us as a sign on our forehead, just as the circumcision was given to Israel: for by it we believers are separated and distinguished from unbelievers. This is the shield and weapon against, and trophy over, the devil. This is the seal that the destroyer may not touch you Exod. xii. 23., as saith the Scripture. This is the resurrection of those lying in death, the support of the standing, the staff of the weak, the rod of the flock, the safe conduct of the earnest, the perfection of those that press forwards, the salvation of soul and body, the aversion of all things evil, the patron of all things good, the taking away of sin, the plant of resurrection, the tree of eternal life.
