Ephesians 1:4; Ephesians 1:13-14

4 Before the creation of the world, he chose us through Christ to be holy and perfect in his presence.
13 You heard and believed the message of truth, the Good News that he has saved you. In him you were sealed with the Holy Spirit whom he promised. 14 This Holy Spirit is the guarantee that we will receive our inheritance. We have this guarantee until we are set free to belong to him. God receives praise and glory for this.
