Christians cannot say but they have had the best teacher; they must therefore walk up to their principles lest they shame their profession, discredit their Master, who seemeth to say to them, as Samson once did to his brethren, Do not you bind me; the Philistines I care not for. Do not you dishonour me, &c.
