In 1 Kings 8 we are told of Solomon praying. Verses 54 & 55 say:
54 And so it was, when Solomon had finished praying all this prayer and supplication to the Lord, that he arose from before the altar of the Lord, from kneeling on his knees with his hands spread up to heaven. 55 Then he stood and blessed all the assembly of Israel with a loud voice, saying:
Solomon went from kneeling on his knees with his hands spread up to heaven, to standing and blessing the people.
Kneeling speaks to me of humility, while hands spread up to heaven speak to me of dependence, a recognition of one’s total need of God. Having postured himself in that way, Solomon was then able to bless the people, give them something that reflected and represented God.
We can only bless people with a life that reflects and represents God if we first kneel and spread our hands up to heaven, if we adopt a posture of humility and dependence on God, acknowledging our utter and complete need of Him.
Kneel and spread your hands to heaven, then you can bless.
