William Tyndale quotes
Mark this also, if God send thee to the sea, and promise to go with thee, and to bring thee safe to land, he will raise up a tempest against thee, to prove whether thou wilt abide by his word, and that thou mayest feel thy faith, and perceive his goodness. For if it were always fair weather, and thou never brought into such jeopardy, whence his mercy only delivered thee, thy faith should be but a presumption, and thou shouldest be ever unthankful to God and merciless unto thy neighbor.
William Tyndale
As Christ compareth the understanding of scripture to a key, so compareth he it to a net, and unto leaven, and unto many other things for certain properties. I marvel, therefore, that they boast not themselves of their net and leaven, as well as of their keys; for they are all one thing. But as Christ biddeth us beware of the leaven of the Pharisees, so beware of their counterfeited keys, and of their false net; which are their traditions and ceremonies, their hypocrisy and false doctrine, wherewith they catch, not souls unto Christ, but authority and riches unto themselves.
William Tyndale
