2 Corinthians 9:5-15 New International Version (NIV)
5 So I thought it necessary to urge the brothers to visit you in advance and finish the arrangements for the generous gift you had promised. Then it will be ready as a generous gift, not as one grudgingly given.
“They have freely scattered their gifts to the poor; their righteousness endures forever.”[a]
1 Declare me innocent, O Lord, for I have acted with integrity; I have trusted in the Lord without wavering. 2 Put me on trial, Lord, and cross-examine me. Test my motives and my heart. 3 For I am always aware of your unfailing love, and I have lived according to your truth. 4 I do not spend time with liars or go along with hypocrites. 5 I hate the gatherings of those who do evil, and I refuse to join in with the wicked.
6 I wash my hands to declare my innocence. I come to your altar, O Lord, 7 singing a song of thanksgiving and telling of all your wonders. 8 I love your sanctuary, Lord, the place where your glorious presence dwells.
25 When the disciples heard this, they were greatly astonished and asked, “Who then can be saved?”
26 Jesus looked at them and said, “With man this is impossible, but with God all things are possible.”
27 Peter answered him, “We have left everything to follow you! What then will there be for us?”
28 Jesus said to them, “Truly I tell you, at the renewal of all things, when the Son of Man sits on his glorious throne, you who have followed me will also sit on twelve thrones, judging the twelve tribes of Israel.
29 And everyone who has left houses or brothers or sisters or father or mother or wife[e] or children or fields for my sake will receive a hundred times as much and will inherit eternal life.

30 But many who are first will be last, and many who are last will be first.
