If I can say one thing about financial support, with the risk of not being completely understood: the priority of giving should be to those who are connected with a local congregation, and not just a ministry. Everyone can ‘start’ a ministry or a business and ask for money, but they may be independent of local oversight and community in the NT Biblical sense. It is much easier to give money for ‘social evangelism’ or some big event, with the hope that someone may get saved if they are treated for their drug abuse or hunger, or have some emotional response to some worldly stimuli, but Yeshua did not commit Himself to man because He knows what is in man: most came to Him because He fed them, not because they wanted HIM. Evangelists and pastors seem to have a natural built-in discord that needs the help of the Holy Spirit to harmonize.
It is much harder to get consistent financial help for existing congregations to not only pay those earning small salaries, but to function as a community to help those in need, train up new and older believers , bless others (including unbelievers) in the name of Yeshua; but maybe even first having to pay the overhead on the place of meeting, which is actually the reverse order.
The Scriptures describing the responsibility of Gentile believers outside of Israel to help those inside is also applicable today. This is the same for Israel as a country: without foreign aid (especially U.S.), Israel would not be able to make it on its own. Such seems to be the way of God for His people, whether Israel, or the Body of Messiah in Israel.
Messianic Jews and Messianic synagogues abroad should also be among the first to help those Jewish believers who live here, just as Cyrus instructed the Jewish people who chose to remain in Babylon and Assyria to help those Israelis who chose to return to the Land following the intended period of exile.
Let those of the household of faith help first of all those with them in the family; there are plenty of others not in the faith helping their household members.
