I may protest too much but your protests are scared hares pulled from your sweaty hat in cold perspiration of desperation.
Why would I be? I believe Jesus's words for why I am guiltless for profaning the sabbath day because He is with me always.
BTW, it would be considered a false witness to tell others you are a sabbath day keeper when no one can testify of themselves as one.
John 5:31 If I bear witness of myself, my witness is not true.
John 7:18 He that speaketh of himself seeketh his own glory: but he that seeketh his glory that sent him, the same is true, and no unrighteousness is in him. 19 Did not Moses give you the law, and yet none of you keepeth the law? .....
You need two or three other witnesses to say that you are a sabbath day keeper.
John 8:17 It is also written in your law, that the testimony of two men is true.
2 Corinthians 13:1This is the third time I am coming to you. In the mouth of two or three witnesses shall every word be established.
But when you speak of Jesus Christ and the Good News to men, that is the only way you can be a true witness, brother. FYI
John 3:28 Ye yourselves bear me witness, that I said, I am not the Christ, but that I am sent before him. 29 He that hath the bride is the bridegroom: but the friend of the bridegroom, which standeth and heareth him, rejoiceth greatly because of the bridegroom's voice: this my joy therefore is fulfilled. 30 He must increase, but I must decrease.
2 Corinthians 4:5 For we preach not ourselves, but Christ Jesus the Lord; and ourselves your servants for Jesus' sake. 6 For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ. 7 But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us.
Something to think about regarding your ministry and service to Him, brother.
