As the psalm closes, we find ourselves a long way emotionally from where we started, but we are echoing the truth of verses 3 and 4. Remember?
PS 22:3 Yet you are enthroned as the Holy One;
you are the praise of Israel.
PS 22:4 In you our fathers put their trust;
they trusted and you delivered them.
PS 22:5 They cried to you and were saved;
in you they trusted and were not disappointed.
The truth of God has not changed – He has always been the God who is holy, the God who rules the nations, the God who can be trusted. But the psalmist is now experiencing that truth and is inviting others to get in on it. All of the earth, rich and poor, all nations and peoples, from now and forever will be told about the Lord. God is not the God who forsakes, but is the God who acts. He is not the God who acts only in the past, but the God who has been good in the present and the God who will be worshipped in the future. The God of "He has done it."
