First day worship is not Biblical.
Matt 26:17
the first day of the feast of unleavened bread the disciples came to Jesus, saying unto him, Where wilt thou that we prepare for thee to eat the Passover?
KJV
There is a translation problem here as Passover is not part of Unleavened Bread as the first day of Unleavened Bread is a high holy day and Passover is not. It is a day to remember or of memorial but not a holy day. This is the first of 12 references to first day in the New Testament. None of which have any reference to first day worship.
Matt 28:1
28:1 In the end of the sabbath, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre.
KJV
This is the second.
Mark 14:12
12 And the first day of unleavened bread, when they killed the passover, his disciples said unto him, Where wilt thou that we go and prepare that thou mayest eat the passover?
KJV
Christ is keeping the laws of His Father.
Mark 16:2
2 And very early in the morning the first day of the week, they came unto the sepulchre at the rising of the sun.
KJV
Nothing about worship here either.
Mark 16:9
9 Now when Jesus was risen early the first day of the week, he appeared first to Mary Magdalene, out of whom he had cast seven devils.
KJV
Nothing about worship here either.
Luke 24:1
24:1 Now upon the first day of the week, very early in the morning, they came unto the sepulchre, bringing the spices which they had prepared, and certain others with them.
KJV
John 20:1
20:1 The first day of the week cometh Mary Magdalene early, when it was yet dark, unto the sepulchre, and seeth the stone taken away from the sepulchre.
KJV
John 20:19
19 Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you.
KJV
At sunset on the seventh day Sabbath starts the first day which this was and they were there were there for fear of the Jews not to worship.
Acts 20:7
7 And upon the first day of the week, when the disciples came together to break bread, Paul preached unto them, ready to depart on the morrow; and continued his speech until midnight.
KJV
We have the same problem here as teaching until midnight is just after the Sabbath and it was most likely a meeting of the elders of the new Church, who the Jews would have been targeting, as they would not go after the rank and file only the elders. He was teaching them the laws of God.
Acts 20:18
18 And when they were come to him, he said unto them, Ye know, from the first day that I came into Asia, after what manner I have been with you at all seasons,
KJV
1 Cor 16:2
2 Upon the first day of the week let every one of you lay by him in store, as God hath prospered him, that there be no gatherings when I come.
KJV
Paul is not even there and many collections were done on the first day of the week.
Phil 1:5
5 For your fellowship in the gospel from the first day until now;
KJV
This is all of the references to the first day and I see no worship services in any of them. Plus there is no foretelling of that change in the Old Testament, which is the telling tale. All other changes were fore told many times and centuries before there implementation.

Does God really judge people on the day that they worship Him? Or is it a lifestyle (all days) of worship that He judges? I may be wrong but I thought it was the heart that God judged man.

The 4th commandment is not about which day God is to be worshiped. It is about rest from work. It is all there in Exodus 20:8-11. God makes no mention of worship there. But this issue has been changed by those who want to take issue with others concerning the day they go to church. It doesn't even seem to matter to them that the commandment makes no mention of worship. It was merely a convenience to meet on that day while they rested. It became a tradition to do so. But real worship takes place from the heart, not from a pew. And real rest does so as well.

For many of us, worship is an every day experience. Rest is another subject altogether. But the real target on the proverbial forehead is on those who feel justified before God by the works they do. The warning in Luke 18:10-14 is clear, in the words of our Lord. He who exalts himself will be abased, he who humbles himself will be exalted. I would rather rest from the works of the law for justification and righteousness (Rom.10:4). These are the works that some need to rest from. God will judge each motive.

This is for you Christians, the battle is beginning now! Obamacare could be the start of the tribulation and the court rulling against us is just the tip of the iceberg. I will now have to find a way to survive without taking the sign of the beast, Obamacare. My God has told me He will never leave me nor forsake me and now all of my trust has to be in Him as I am unable to with stand this on my own.

You have to find a way to survive, and yet you have to trust Him? Make up your mind. This is an appropriate contradiction. It demonstrates what we have been enduring from you. The name for it is leaven. The leaven of the law. It happens when the two covenants are mixed together and one becomes double minded. On the one hand, one claims to trust in Jesus for salvation and life, and on the other hand one is doing works for the purpose of his own survival from God's wrath.

One day a week worship is an OT concept. We are to walk in the Spirit at all times every day. That is our worship.

Joh_4:24 God is a Spirit: and they that worship him must worship him in spirit and in truth.

This should be compared to those who seek to worship in a physical way one day a week..

Mat_15:9 But in vain they do worship me, teaching for doctrines the commandments of men.

Our worship of God should be a constant thing and not just one day a week. Daily I praise God and recognize His greatness, while also recognizing that there are no words capable of giving Him the praise He rightfully deserves.

I don't have a "day of worship"; I worship Him daily.

Why do we major in shadows and minor in substance?
Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: Which are a shadow of things to come; but the body is of Christ.
(Col 2:16-17)

Amen to this!
