Smith encouraged use to remember that God works "in us," "for us" and "through us" as we serve Him.
How do we serve Him?
By Identifying our passions, our experiences and our gifting, and using them to share God's love, mercy and truth with others.
Apart from Him we could not do that.
But God, in His love and rich mercy has made us alive together with Christ (Ephesians 2:5) and that's all we need!
