The sacrifice which God accepts is that of His Son, Jesus Christ. No other sacrifice is needed. Our belief that Jesus’ sacrifice is acceptable to God is the faith which saves us from eternal separation from the Father. To the extent that we trust in Jesus’ blood covering our sins, we please God.
God speaks to us, “This is the covenant I make with [you]. I put My laws on [your] hearts and write them on [your] minds. I never again remember [your] sins and lawless acts.” (Hebrews 10: 16 – 17)
“Keep your attention on Jesus Christ, as risen from the dead.” (2 Timothy 2: 8) Christ is seated at the right hand of His Father, interceding for you.
“For if [you] die with Him, [you] also live with Him. If [you] endure, [you] also reign with Him; if [you] deny Him, He also denies [you]; if [you] are faithless, He remains faithful, for He cannot deny Himself.” (2 Timothy 2: 11 – 13)
