The answer to the above question is simple. I am a follower of Yahweh, God of Scripture. I want to love God and bring Him glory in my entire life. He gives me commandments to meet with other believers on specified days (Lev. 23) and I am told not to forsake to assemble myself with the brethren as the manner of some is (Heb. 10:25). I obey God, not out of a rigid "have to" but out of a desire or want to do so. I enjoy being obedient to the Father's word because He has given me a new heart and mind that has the propensity to do what is righteous.
Yeshua attended synagogue service on the Sabbath, and it was his customary practice (Lk. 4:16). If we are followers of him (following his example) we should do the same.
