So, you choose one that is written in an archaic dialect of English? You have to translate the KJV into modern English to get it to make sense. Maybe if you are teaching the "Law" or the Old Testament. You did hear the good news that we are FREED from sin and the Law, right? I mean, you aren't living your life UNDER the old law still are you? Jesus completely fulfilled the requirements of the Old Law and gave us a NEW Law. In fact, the scriptures refer to that "Old Law" as the Law of Death and our New Law as the Law of Life.
Now, which do you choose? Living under the Law, or living under Grace? You can't have both!
Romans 7:1 Do you not know, brothers—for I am speaking to men who know the law—that the law has authority over a man only as long as he lives? 2 For example, by law a married woman is bound to her husband as long as he is alive, but if her husband dies, she is released from the law of marriage. 3 So then, if she marries another man while her husband is still alive, she is called an adulteress. But if her husband dies, she is released from that law and is not an adulteress, even though she marries another man. 4 So, my brothers, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit to God. 5 For when we were controlled by the sinful nature, the sinful passions aroused by the law were at work in our bodies, so that we bore fruit for death. 6 But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code.NIV
You see, we don't have to be "Protestants", we just need to live a life of LOVE and FREEDOM. No, that does not mean that I rest on Saturday. Do you not know Jesus' acid test for disciples? It has NOTHING to do with keeping the Sabbath. If you haven't figured out what it is, I will point you to a scripture that explains it perfectly. But really, we no longer need the Sabbath. You see, in the OT God wanted a tenth of everything including our time. However, we have a seven day week, so he took a day. In the NT, God wants OUR HEARTS. IOW, he is not satisfied with a mere %10, HE WANTS IT ALL. Not only is the last day of the week dedicated to God, but so are Sunday thru Friday!
So why do most churches meet on the FIRST day of the week?
Acts 20:7 On the first day of the week we came together to break bread. Paul spoke to the people and, because he intended to leave the next day, kept on talking until midnight. NIV
I Corinthians 16:2 On the first day of every week, each one of you should set aside a sum of money in keeping with his income, saving it up, so that when I come no collections will have to be made. NIV
I believe that this came from the fact that Jesus rose from the dead on the first day of the week which is probably why they celebrated communion (see Acts 20:7) on Sunday.
John 20:1 Early on the first day of the week, while it was still dark, Mary Magdalene went to the tomb and saw that the stone had been removed from the entrance. NIV
And Jesus appeared to them on the first day as well.
John 20:19 On the evening of that first day of the week, when the disciples were together, with the doors locked for fear of the Jews, Jesus came and stood among them and said, "Peace be with you!" NIV
Now, if you still don't understand this concept of being FREE from the law, I have a reading assignment for you. Read all of Romans 6, 7 and 8 in a version OTHER than the KJV. Soon, you will find that the Spirit can work through ANY translation, so pick one that speaks YOUR language.
