The only remedy for sin is a sinless2,5 Jesus Christ1,2,3,4,5,6,7,8,9. His coming in the flesh3,5,9, His death7,8 and sacrifice of His own blood2, together with His triumphant victory over death4,7 is the remedy for sin. He “condemned” sin3, bore it for all8, and was “vitorious” over it4, taking them away5.
Being in the flesh3, we are enslaved to sin7 and death4. The only remedy for sin for us — receiving forgiveness6 and advocacy1 — is to die with Him (in baptism)7, raised to walk in the Spirit3 and wait eagerly for His saving return8,9.
