We can acknowledge God in recognizing God's holiness and majesty.

Our service to God can be offering ourselves in providing services to others or just being there to give encouraging words or even giving a financial blessing.

Reverence in God is obeying His voice, keeping His commandments and turning from evil. 

We can worship God through reverence, service, and acknowledgement.

God told Moses to tell Pharoah to let His people go worship Him in the wilderness for 3 days.  (Exodus 5:3)Jesus died and rose again on the 3rd day. Luke (24:46)
