Hebrews 6:1-15

Not Only the Foundation, Build the House

we have the first principles as the foundation, but the higher doctrine ought immediately to follow which is to complete the building. They then act most unreasonably who remain in the first elements, for they propose to themselves no end, as though a builder spent all his labor on the foundation, and neglected to build up the house. So then he would have our faith to be at first so founded- John Calvin on Hebrews 6
