Sinful examples are very enticing and encouraging; many have found it so to their eternal undoing. Those that have no ears to hear what you say have many eyes to see what you do. Bad princes make bad subjects, bad masters make bad servants, bad parents make bad children, and bad husbands make bad wives. It is easier for the bad to corrupt the good than for the good to convert the bad. It is easier to run down the hill with company than to run up the hill alone.
Evil company, commonly termed goodfellows, but indeed the devil's chief instruments to hinder a wretched sinner from repentance and piety. The first sign of God's favor to a sinner is to give him grace to forsake evil companions.
Angels are exact and careful observers and eyewitnesses of our behavior and deportment in the public ordinances. To this end were the curtains of the tabernacle pictured: full of cherubim to signify that about our solemn meetings, whole troops of angels take notice of our behavior. Surely, if this were considered, we should be very serious in God's worship. Yea, how spiritual and heavenly should we be if our hearts were but fixed on these glorious angels?Communion with Angels, 100
