Had there been no cross and bloodshed of the Lord Jesus Christ, we would have been in the kingdom of Satan and his dominion all through our life. It is His blood that has opened up a great way eternally to seek the kingdom of God. The death of Christ marked an essential purpose for the entire world so that God would be pleased with the participation of His people in worshipping Him in spirit and truth.
Paul in Acts 20:28 tells “Be on guard for yourselves and for all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood” (ESV). Jesus Christ has redeemed us from the clutch hold of eternal damnation and brought to eternal life by His substitutionary death. Thus our redemption has come through Jesus’s death.
