If thou choosest the ungodly for thy friends, thou art in danger of suffering, as well as of sinning with them. The wheat has many a blow for being among the chaff. The gold would not be put into the fire if it were not for the dross with which it is mingled.
The first and the great work of a Christian is about his heart. Do not be content with seeming to do good in “outward acts” while your heart is bad, and you are a stranger to the greater internal heart duties.
