An encouraging quote from Mr. Weak - Pilgrim's Progress by John Bunyan
"I am resolved to keep in the good way, to run when I can, to walk when I cannot run, and creep when I cannot walk; yet to keep my face toward Zion. My journey may be long and toilsome, and my mind and body weak; yet my heart is set on that fair City at the end of the way, beyond the river that has no bridge."
There are seasons in our life where sanctification is happening faster than others times...the important thing is that we continue to press on in our pursuit of Christ more and more each day. The true Christian perseveres, even if it means crawling at times.
