"(Acts 2:33) Christ first purchased man's redemption by His atoning death and resurrection. Then He ascended to His Father in heaven and there presented the blood that was the evidence and seal of redemption. Upon the Father's acceptance of the blood, Christ received from the Father the gift of the Holy Spirit to pour out upon those who believed in Him".
