The wise men traveled over 900 miles so that they could come and worship the King. As they worshiped Him with tremendous joy in their heart, they opened up the best of what they had as they gave it to Jesus. Giving is an act of worship that is driven by love. We love, because God first loved us.
Lifting up our hands before a holy God is a posture of worship. Throughout Scripture we see examples of people lifting up hands as they worship God. Why is it that God wants us to lift our hands to him? We come to worship God as we lift up holy hands as we surrender and draw near to God, as we praise His name, as we do battle and find victory in God.
