Yes. It is all one plan unfolding. The purpose of the plan? I know the one He showed us, and quite clearly----to rescue a people out of the kingdom of darkness and bring them into the kingdom of the Son. There are two kingdoms, the kingdom of darkness and the kingdom of light. King Jesus the Christ is King of the Kingdom of Light. It is ultimately the whole redeemed world, (at that time, the time of His second coming, there will be only the redeemed in the world. ) And He rules now from heaven and within the hearts and lives of those who are His, until the time of Satan's utter and final destruction. Then there will be one kingdom, the kingdom of Light. Col 1:13-14; Eph 2:1-9. Those whom He has redeemed are the people of His kingdom.
