Our first and primary obligation is certainly to the local church. The Bible is very clear on the fact that we are to financially support those pastors who minister to us spiritual things, by ministering to their physical needs (1 Corinthians 9:7-11; 1 Timothy 5:17-18). The Scripture is equally plain regarding our obligation to support the poor and needy within the body of Christ (1 Timothy 5:16; 1 John 3:17).
And Lot lifted up his eyes and saw that the Jordan Valley was well watered everywhere like the garden of the Lord, like the land of Egypt, in the direction of Zoar. (This was before the Lord destroyed Sodom and Gomorrah.) So Lot chose for himself all the Jordan Valley, and Lot journeyed east. Thus they separated from each other (Genesis 13:10-11). Abraham and Lot now face the opposite temptation from what they faced in chapter 12, when there was a famine in Canaan; now they experience the equally great challenge of prosperity in Canaan.
