Acts 20:33-34, Gal 4:19, 1 Thess 2:19, Phil 4:1

Paul earned the money he needed to preach the gospel. He did not burden the saints with finances. (Act 20:33-35)

Act 20:33 I have coveted no man's silver, or gold, or apparel. 34 Yea, ye yourselves know, that these hands have ministered unto my necessities, and to them that were with me. 35 I have shewed you all things, how that so labouring ye ought to support the weak, and to remember the words of the Lord Jesus, how he said, It is more blessed to give than to receive.

Because what Paul wanted was not wealth, but that the souls of the saints would grow in Christ. (2 Cor 12:14-15, Gal 4:19, Phil 4:1, 1 Thess 2:19)

2 Cor 12:14 Behold, the third time I am ready to come to you; and I will not be burdensome to you: for I seek not yours but you: for the children ought not to lay up for the parents, but the parents for the children. 15 And I will very gladly spend and be spent for you; though the more abundantly I love you, the less I be loved.

Gal 4:19 My little children, of whom I travail in birth again until Christ be formed in you,

Phil 4:1 Therefore, my brethren dearly beloved and longed for, my joy and crown, so stand fast in the Lord, my dearly beloved.

1 Thess 2:19 For what is our hope, or joy, or crown of rejoicing? Are not even ye in the presence of our Lord Jesus Christ at his coming?
