First, I found an amazing number of defenses of the practice online. The best explanation of why people lift their hands in worship came from here.
- Lifting the hands is a symbol of surrender.
- Lifting the hands is a symbol of trust.
- Lifting the hands is a symbol of openness.
- Lifting the hands is a symbol of affection.
In looking through scripture, there appears to be three classifications for the raising of hands:
1. Prayer (5 references): 1 Timothey 2:8, Lamentations 3:40-42, Psalm 28:1-2, Psalm 141:1-2, Nehemiah 8:5-6
2. Worship (2 references): Psalms 63:3-4, Psalm 134:1-3
3. Study (1 reference): Psalm 119:48
The Hebrew word for hand is the word yad; yadah means to “throw out the hand” or to worship with extended hands.Which may indicate that the extension of hands to an object of adoration is simply an assumption of Hebrew culture.
Another article noted one other aspect of the raising of hands - which C.S. Lewis also applies to kneeling in The Screwtape Letters - is that movements and positions of the body influence the attitude of the mind and heart.
But of note also is this article which makes the claim that all raising-of-hands references in the old testament are related to the sacrificial system, and thus are inappropriate to a Christian world where sacrifices have been fulfilled by the death and resurrection of Christ. The author dismisses the 1 Timothy 2:8 scripture as a figurative passage asking for "clean hands" of Christians.
For me, this study has been a comfort. It reminds me that my own prejudices should not rule how I view others, or their relationship with God. Surely, some raise their hands to be showy. But others do so with sincere hearts, looking to praise God and obey scripture.
