Seems there is a LOT of guessing—and a little hate speech
Raising ones HANDS in church is a pretty common gesture. Raising a fist sounds rather strange.
The Apostle Paul wrote to Timothy: “I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks . . . I will therefore that men pray every where, lifting up holy hands, without wrath and doubting” (First Timothy 2:1–4, 8).
In the Scriptures, the outstretched arm was symbolic of seeking God’s mercy and blessing. This position of prayer reflects the beatitude of being a peacemaker and expresses the following attitudes: It appeals to God’s sovereign power.
In the Jewish faith, before Pharaoh released the people of Israel from slavery, God sent ten plagues to the nation of Egypt. God thus demonstrated His ownership over all creation. When Pharaoh pleaded with Moses to ask God to stop the hailstorm, “Moses said unto him, As soon as I am gone out of the city, I will spread abroad my hands unto the Lord; and the thunder shall cease, neither shall there be any more hail; that thou mayest know how that the earth is the Lord’s” (Exodus 9:29).
When the Israelites fought against the Amalekites in the wilderness, Moses stood on a hill overlooking the battlefield with his arms outstretched, holding the rod of God: “It came to pass, when Moses held up his hand, that Israel prevailed: and when he let down his hand, Amalek prevailed” (Exodus 17:11).
It reflects God’s redeeming work: salvation.
Recalling God’s provision for past needs renews our faith in present situations. Moses often called the people of Israel to remember the great works God.
Before Israel entered the Promised Land to conquer it, Moses encouraged them not to fear the mighty inhabitants of the land: “Thou shalt not be afraid of them: but shalt well remember what the Lord thy God did unto Pharaoh, and unto all Egypt; the great temptations which thine eyes saw, and the signs, and the wonders, and the mighty hand, and the stretched out arm, whereby the Lord thy God brought thee out . . .” (Deuteronomy 7:18–19).
It demonstrates worship and petitions God’s blessing.
When King Solomon dedicated the Temple to God, he sought God’s blessing on it. “Solomon stood before the altar of the Lord in the presence of all the congregation of Israel, and spread forth his hands toward heaven: and he said, Lord God of Israel, there is no God like thee, in heaven above, or on earth beneath, who keepest covenant and mercy with thy servants that walk before thee with all their heart . . . . O Lord my God, . . . hearken unto the cry and to the prayer, which thy servant prayeth before thee today: that thine eyes may be open toward this house night and day, even toward the place of which thou has said, My name shall be there . . .” (I Kings 8:22–23, 28–29).
Hope this helps
