“Truly my soul waiteth upon God: from him cometh my salvation.”
To wait upon our Father can mean many different things. In these end times we wait for the Return of Jesus Christ who paid for our Salvation with His sacrifice on the Cross.
‘Waiting for the Lord‘ can also be waiting for understanding of His Word, maybe spiritual comfort concerning a life decision you are praying about.
Whatever it is, never rush it. Think over what you are waiting for, do your part and then do it some more. Pray about it and then pray about it some more and always ask our Father for direction and ask that His Will be done.
