Not by might, nor by power, but by my spirit, saith the Lord of hosts. (Zechariah 4:6)
And I was with you in weakness, and in fear, and in much trembling. And my speech and my preaching was not with enticing words of man’s wisdom, but in
demonstration of the Spirit and of power: That your faith should not stand in the wisdom of men, but in the power of God. (1 Corinthians 2:3-5)
Except the Lord build the house, they labour in vain that build it. (Psalm 127:1)
I have planted, Apollos watered; but God gave the increase. So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase. (1 Corinthians 3:6-7)
I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. (John 15:5)
