Greetings again markalan,
I consider what you state above are a significant part of the two parts of the Gospel of the Kingdom and Name,
Acts 8:5–6,12 (AV): 5 Then Philip went down to the city of Samaria, and preached Christ unto them. 6 And the people with one accord gave heed unto those things which Philip spake, hearing and seeing the miracles which he did. 12 But when they believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ, they were baptized, both men and women.
Yes, a true understanding of what was accomplished in the suffering, death and resurrection of Jesus is important and forms part of the things concerning the Name of Jesus Christ. We participate in this process by an affectionate belief which leads to water baptism for the identification with his death and resurrection as stated in my earlier post.
This participation is only the start of our walk in Christ and for the rest of our lives we need to live a crucified / resurrected life motivated by the love of Christ.
.
Galatians 2:20 (AV): I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
Kind regards
Trevor
