I really like Carolyn Brown's suggestion for this Psalm today, you can find her blog here
or you could go with this....
Leader: The Lord is life and light and love!
Children: The Lord is home! Safe! Our base and secure place.
All: Of whom shall I be afraid?
Leader: The Lord will hide us in the day of trouble
Children: He will hide us in his tent
All: We will not be afraid of our enemies.
Leader: The Lord will set us high on a rock
Children: We will be high up out of harm's way
All: And we will praise God with shouts of joy
Leader: Come and be intimate with the Lord our God
Children: Let our hearts look for God's face.
All: We seek the living God who is light and love.
