Gordon Palmer Confirms that Reciprocity is Gods Sufficiency II Cor 9:5-15

You have to personally purchase the videos in order to re-load, therefore, that would mean that the laborer is worthy of his/her hire [I Cor. 9:1-14 focus verses 11-14]. I also means that when you are expanding the gospel for others, and they reap the benefit from your advertising and promotions, it would be the will of God to do as Paul sought before hand the sufficiency to helped the pre-arriving brother/sisters to abound in the Grace of Gods ministry works.

[II Cor 9:5-15] focus 8,10,12. I am proud to see how the ordination of God's word sown in to the kingdom, reaps a harvest of royalties for those that are expanding the gospel.  You have confirmed that God has a reciprocity an indemnity principal installed in the practice/works for those that preach the gospel. 
An indemnity is a sum paid by A to B by way of compensation for a particular loss suffered by B. The indemnitor (A) may or may not be responsible for the loss ..security or protection against a loss or other financial burden.
Paul spoke it best in [ II Cor 9:5] Therefore, I thought it necessary to exhort the brethren [adelphos, pronounced ad-el-fos]  Greek work meaning as connective particle,or a community based on identity of origin life.

[I Cor.12:28-31; II. Cor. 9:1-15; Eph. 4:11-16]. Thank you for your uploads, and advancing the prophetic word 
In the book of Matthew, 12:50 Jesus spoke it better, and said, "for whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother" which is the equivalent to spiritual kinship with the infinity marked by fulfillment of the will of the Father

LUKE 8:21 And my brethren are these which hear the word of God, and do it.
