Ponder this meanwhile:
Of avoiding many Words.
Fly the tumult of the world as much as thou canst; for the treating of worldly affairs is a great hindrance, although it be done with sincere intention;
For we are quickly defiled, and enthralled by vanity.
Oftentimes I could wish that I had held my peace when I have spoken; and that I had not been in company.
Why do we so willingly speak and talk one with another, when notwithstanding we seldom cease our converse before we have hurt our conscience?
The cause why we so willingly talk, is for that by discoursing with another we seek to receive comfort one of another, and desire to ease our mind wearied with many thoughts:
And we very willingly talk and think of those things which we most love or desire; or of those things which we feel to be against us.
But alas, oftentimes in vain, and to no end; for this outward comfort is the cause of no small loss of inward and divine consolation.
Therefore we must watch and pray, lest our time pass away idly.
If it be lawful and expedient for thee to speak, speak those things that may edify.
Evil habit and neglect of our own growth in grace do give too much liberty to inconsiderate speech.
Yet discourse of spiritual things doth greatly further our spiritual growth, especially when persons of one mind and spirit associate together in God.
