Brian Devany, pastor of Manor Fellowship has a good friend from Israel who is a Messianic Jew and part of the Jews for Jesus ministry. He is going to be in the Austin area the week of April 4th-10th and is available to perform the Christ in the Passover or even preach a message on Sunday morning. More information is available on Jews for Jesus website. They do request a love offering be taken up which usually just covers the travel expenses of the guy coming in.
While this is several months away, his schedule usually is booked several months before Passover. If you are interested, please contact Brian directly and he will put you in touch.
