1 Peter 1:22-23
Seeing you have purified your souls in obeying the truth through the Spirit to unfeigned love of the brothers…
In passing from nature to grace you did not pass from a lower to a higher stage of the same condition — from daybreak to sunshine, but from darkest night to dawn of day. Unlike the worm which changes into a winged insect, or the infant who grows up into a stately man, you became, not a more perfect, but a "new creature" in Jesus Christ.
(T. Guthrie, D. D.)
