“Therefore let all the house of Israel know with certainty that God has made this Jesus, whom you crucified, both Lord and Messiah!”
Jesus is Savior and Lord. He is the One who saves and the One who rules. You cannot parcel out which parts you like. You cannot claim Him as Savior and reject Him as your Lord. He is not received on those terms. He is both Lord and Savior. If you receive Him, you receive His forgiveness AND His reign and rule over what used to be your life, but now is His. If you are bought back (redeemed) then you are owned, but have faith, you have a gracious Owner.
