God declared that all who sin will die, both physically and spiritually. This is the fate of all mankind. But God, in His grace and mercy, provided a way out of this dilemma, the shed blood of His perfect Son on the cross. God declared that “without the shedding of blood, there is no forgiveness” (Hebrews 9:22), but through the shedding of blood, redemption is provided. The Law of Moses provided a way for the people to be considered “sinless” or “right” in God’s eyes—the offering of animals sacrificed for every sin they committed. These sacrifices were only temporary, though, and were really a foreshadowing of the perfect, once-for-all sacrifice of Christ on the cross (Hebrews 10:10).
This is why Jesus came and why He died, to become the ultimate and final sacrifice, the perfect (without blemish) sacrifice for our sins (Colossians 1:22; 1 Peter 1:19). Through Him, the promise of life eternal with God becomes effective through faith to those who believe in Jesus. “So that what was promised, being given through faith in Jesus Christ, might be given to those who believe” (Galatians 3:22). These two words, faith and believing, are critical to our salvation. It is through our believing in the shed blood of Christ for our sins that we receive eternal life. “For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God—not by works, so that no one can boast” (Ephesians 2:8–9).
