An invocation is usually a prayer that, in some liturgies, takes place towards the beginning of Lord's Day worship, other worship settings, or public gatherings. It is a formal calling upon the name of God, to ask for his presence in worship and for him to hear petitions lifted up in prayer. An entire prayer can be designated as an 'invocation' or prayers may contain invocations. Invocations are found throughout Scripture, a well known invocation is the opening lines of the Lord's Prayer which says, 'Our Father which art in heaven, hallowed be thy name..." (Mt. 6:9)
Examples of Biblical Invocations
Psalm 103:1 - Bless the LORD, O my soul: and all that is within me, bless his holy name.
Matthew 28:19 - Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.
