Why do Church of God members worship Saturday?

It is very common custom among Christianity to worship God on Sunday. But we can't have blind faith like a blind mind who bases his judgements based on a dogs decision and follow everyone else because the salvation of our souls is very important. Is Sunday worship something that is based on the Bible? Even 2,000 years ago Jesus Christ rebuked those who thought they knew more than God Himself about the Scriptures:

Jn 5:39 "Jesus replied, “Your mistake is that you don’t know the Scriptures, and you don’t know the power of God.

Then what does the Scripture say about the day to worship God? Of course we can pray to God whenever we feel like, however, if we truely beleive in God we need to follow His commandments because He will save us, NOT what we think.

Ex 20:4 " “Remember to observe the Sabbath day by keeping it holy... That is why the Lord blessed the Sabbath day and set it apart as holy."

God promised us to make us Holy on the Sabbath day which is the "7th Day of the week" What day is the "7th Day of the week"

–noun 1. the first day of the week,

Let us use the Bible to confirm the FACT that Saturday is the 7th Day NOT SUNDAY as most beleive.

It is clear that Sunday is NOT the Seventh day of the week, but rather IT'S THE FIRST (1ST) DAY OF THE WEEK, a day where God promised no blessings at all. Then why Do most Christians worship on Sunday if it's not something which is Biblical based?

IS 29:13 The Lord says:
"These people come near to me with their mouth
and honor me with their lips,
but their hearts are far from me.
Their worship of me
is made up only of rules taught by men

Do not follow rules taught by men, follow Father and Mother who allow us to keep the Sabbath day Holy as a precious promise to give us rest blessings and holiness (Gen 2:1). On our next post, let us see confirmation that the Apostles and Christ Himself kept the Sabbath day Holy.
