Was the thief suffering by Messiah’s side saved by faith or works?
Upholding Messiah’s Law is only possible by the one redeemed through faith in Jesus as Lord and possessing the Spirit of God as Teacher, Intercessor, Guarantor of relationship, forever. Until such time relationship is established by faith, alone, in Messiah, it matters not works or laws or ideology one follows.
Jesus must be first and He can only become Lord, Messiah, God, by faith…just as the thief on the Cross discovered, there is nothing we can do to garner God’s favor but believe in Jesus as God who died to pay our sin-debt (John 3:16). Our good works will follow when the Spirit is our Sanctification and our Guarantor of relationship (Ephesians 1:13-14).
If man could find righteousness with the Father through obedience, Jesus would not have needed to suffer and die (Galatians 2:21).
