There are three general leaders in Jewish Worship.
Rabbi: This is a person trained in Jewish law, ritual, and tradition and ordained for leadership of a Jewish congregation (especially one serving as chief religious official of a synagogue). The Rabbi will often give the D'var Torah or Sermon to the Congregation and serve as a general spiritual leader.
Hazan/Cantor: The Hazan is responsible for leading the communal praying by singing the prayers. Any knowledgeable congregant may serve as a temporary Hazan, but most synagogues have a permanent Hazan, at least on Sabbath and festivals.
Ba'al Qoreh: This person specifically reads the Torah in front of the congregation at the certain times of the service where it is possible. The function of Ba'al Qoreh is often merged into the Rabbi's or Hazan's duties.
Jews do not worship human beings. Jews worship only God.
Generally, the Rabbi leads Jewish worship services.
Communal Jewish worship services may be led by any adult Jew knowledgeable in the liturgy. Ordination is not required. The liturgy is sufficiently complex that rabbis, who are trained in Torah, Talmud and Jewish law, can and usually do lead many services. Rabbinic training generally emphasizes scholarship over performance, so larger congregations frequently hire a cantor specifically to lead services. Cantoral training focuses on the performance aspects of the liturgy.
The pastor and the worship leader(music director, usually) plan the service then the worship leader guides the congregation and lay leaders in the worship. The pastor gives the message(sermon) and invitation.
Jews do not worship "activities"; they worship the singular God.
Only if you do not have a spirtual, mature praise and worship leader.
Jews face in the direction of Jerusalem when they worship.
The Jewish house of worship is called synagogue, although Jews can worship G-d anywhere at any time.
Jews worship in synagogues. there are synagogues wherever Jews live throughout the world.
None as Jews do not worship any physical items.
The Jews do not worship ANY people. Worshipping people is a violation of Jewish law. Jews only worship God.
The Jewish people worship God in whichever country they live in. They also believe in Christ but do not worship Him. Some countries where the Jews live may ban worship altogether, but Jews can worship in their mind.
Jews worship God whether or not synagogues are available.
God is the leader of worship ina church
A worship leader is not there to do a Christian Rock concert. A worship leader is not there to show off their voice, guitar skills, or whatever. A worship leader is not there to put on a show. A worship leader is there to lead the congregation into worshiping the Almighty. Leading people into the very presence of God. The worship leader should be praising the Lord in song and in prayer, and the praise team should be joining the worship leader. The leader and the team then invite the rest of the congregation to worship with them. If the leader and team is not there to do that, they are a failure.
