We need God. It doesn’t matter how strong or powerful we think we are, we need Him. See Psalm 21.
For the king trusts in the Lord , And through the lovingkindness of the Most High he will not be shaken.
Psalms 21:7 NASB
Even the king, the most powerful, authoritative person they knew admitted that he needs the Lord. The king is not shaken because of the Lord, so how much more will that be the case for us? Are we trusting in the Lord for the strength that we need to do everything today?
