The "but" says it all!
SDA doctrine, the Mark of the Beast (Sunday worship), Seal of God (Sabbath worship)
Mark of the Beast - all with the mark are condemned!
Bottom line - the discriminator between the lost and the saved is what day you worship!!!!
(According to SDA doctrine, that is).
Yet, we know that the Seal is the Holy Spirit, "30 And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption." Eph 4:30
NOT what day of the week we worship!!!!!!!!!
And how is this achieved: "8 For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, 9 not of works, lest anyone should boast. 10 For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them."
Furthermore, "14 For as many as are led by the Spirit of God, these are sons of God. 15 For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, “Abba, Father.” 16 The Spirit Himself bears witness with our spirit that we are children of God, 17 and if children, then heirs—heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together." Rom 8:14-17
If Sabbath worship was as crucial to salvation as is so strongly asserted by Adventists one would think that all the New Testament writings would be absolutely replete with dozens of explicit warnings not to neglect this crucial observance!
Yet they are just not there.................................
