Luke 6:38 (NLT) If you give, you will receive. Your gift will return to you in full measure, pressed down, shaken together to make room for more, and running over. Whatever measure you use in giving – large or small – it will be used to measure what is given back to you."
2 Corinthians 9:7 (NLT) You must each decide in your heart how much to give. And don't give reluctantly or in response to pressure. "For God loves a person who gives cheerfully."
2 Corinthians 8:16-24 (NLT)
16 I am thankful to God that he has given Titus the same enthusiasm for you that I have.17 He welcomed our request that he visit you again. In fact, he himself was eager to go and see you. 18 We are also sending another brother with Titus. He is highly praised in all the churches as a preacher of the Good News. 19 He was appointed by the churches to accompany us as we take the offering to Jerusalem – a service that glorifies the Lord and shows our eagerness to help. 20 By traveling together we will guard against any suspicion, for we are anxious that no one should find fault with the way we are handling this generous gift. 21 We are careful to be honorable before the Lord, but we also want everyone else to know we are honorable. 22 And we are also sending with them another brother who has been thoroughly tested and has shown how earnest he is on many occasions. He is now even more enthusiastic because of his increased confidence in you. 23 If anyone asks about Titus, say that he is my partner who works with me to help you. And these brothers are representatives of the churches. They are splendid examples of those who bring glory to Christ. 24 So show them your love, and prove to all the churches that our boasting about you is justified.
