God's Challenge: Prepare for Worse Trials

Jeremiah 12:5-6

If thou hast runne with the footemen and they haue wearied thee, then howe canst thou match thy selfe with horses? and if thou thoughtest thy selfe safe in a peaceable lande, what wilt thou do in the swelling of Iorden?

For euen thy brethren, and the house of thy father, euen they haue delt vnfaithfully with thee, and they haue cryed out altogether vpon thee: but beleeue them not, though they speake faire to thee.
