Diaspora prayer was modeled on Temple worship but gradually evolved during the Middle Ages, incorporating new elements of praise and supplication. The liturgy reached its final form about a century ago but has had the same general outline for over a millennium. The main themes are thanks to God for His blessings; praise for God’s greatness, power, mercy, and forgiveness; supplication for peace, health, wisdom, etc.; and prayer for the coming of the Messiah (or the Messianic Age). The Sh’ma, recited daily, is Judaism’s ultimate proclamation of God’s unity and divinity: Hear, O Israel: The Lord is our God, the Lord is One (Deuteronomy 6:4)
