It is a poetical thought that God is dormant or "asleep" when He doesn't respond readily to the needs of His people - when He seemingly appears to be unconcerned with their troubles. It is then that they have to awaken Him to activity with their cries. Both Asaph and Isaiah prayed the most powerful prayers to "awaken" God's power on the behalf of His people. But, in relation to the Church of today, is it God Who is "asleep" here? What do you suppose is His response to these prayers concerning the Church of today? Isaiah 52:1 gives His response. It is not God Who sleeps. The one to "awake" is "Zion" - His church!
