The love which (early Christians) felt towards the Lord was not a quiet emotion
which they hid within themselves in the secret chamber of their souls, and which they only spake of in their private assemblies when they met on the first day of the week, and sang hymns in honour of Christ Jesus the crucified, but it was a passion with them of such a vehement and all-consuming energy, that it was visible in all their actions, spoke in their common talk, and looked out of their eyes even in their commonest glances. Love to Jesus was a flame which fed upon the core and heart of their being; and, therefore, from its own force burned its way into the outer man, and shone there. Zeal for the glory of King Jesus was the seal and mark of all genuine Christians.
