I had this tucked away in my writings. I don't have a clue who wrote it, maybe a Puritan? In any case it's beyond my style or ability. I thought I'd pass it along..
"Here is the spring where waters flow,
to quench our heat of sin
Isa. 12:3 and 49:10; Rom. 5:16 and 6:17) Here is the tree where truth doth grow,
to lead our lives therein
Jer. 33:15 and Ps. 119:160) Here is the judge that stints the strife,
when men’s devices fail
Rev. 2:7 and 22:2; Ps. 119:142,144) Here is the bread that feeds the life,
that death cannot assail.(John 6:35) The tidings of salvation dear,
comes to our ears from hence
Luke 2:10) The fortress of our faith is here,
and shield of our defense.(Eph. 6:16) Then be not like the hog that hath
a pearl at his desire,(Matt. 7:6) And takes more pleasure in the trough
and wallowing in the mire.(2 Pet. 2:22) Read not this book in any case,
but with a single eye
Matt. 6:22) Read not but first desire God’s grace,
to understand thereby.(Ps. 119:27,73) Pray still in faith with this respect,
to fructify therein,(Jude 20) That knowledge may bring this effect,
to mortify thy sin.(Ps. 119:11) Then happy thou in all thy life,
what so to thee befalls.(Josh. 1:8) Yea, double happy shalt thou be,
when God by death thee calls."
