The main thing we need now is prayer. Prayer that on Sunday God is gracious to send us an overcast but cool and dry day, that His presence would be so with us that lives are changed by that very fact. In this whole project, our heart's desire is that this would be a place that is pleasing to God foremost and that it would be a place that helps one feel His presence.
Psalm 143:10
10 Teach me to do your will,
for you are my God;
may your good Spirit
lead me on level ground.
Acts 2:28
28You have made known to me the paths of life;
you will fill me with joy in your presence.
Hosea 6:2
2 After two days he will revive us;
on the third day he will restore us,
that we may live in his presence.
