"Keeping the Church Pure"

1 John 2:15 
Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.

Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord.
I Corinthians 15:58

But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light;  1 Peter 2:9 

And he said, Thou hast asked a hard thing: nevertheless, if thou see me when I am taken from thee, it shall be so unto thee; but if not, it shall not be so.  II Kings 2:10

 And he said, The things which are impossible with men are possible with God. 
Luke 18:27

Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.  Mark 11:24

But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed.  James 1:6

If ye shall ask any thing in my name, I will do it.  John 14:14

And she shall bring forth a son, and thou shalt call his name Jesus: for he shall save his people from their sins.
Mattiew 1:21
