1 Timothy 3:15

But if I tarry long, 
that thou mayest know how thou oughtest to behave thyself in the house of God, which is 

the church of the living God, 

the pillar and ground of the truth.

Acts 20:28

Take heed therefore unto yourselves, 
and to all the flock,

over the which the Holy Ghost hath made you overseers, 

to feed the church of God, 
which he hath purchased with his own blood.
