All blessings comes from God, not from men. Then, is it enough to receive God's blessing when you know that God exists? Not at all.
God's blessing will be given us when we come to God through worship. However, we have to come to God following God's commands, not insisting our own ways. Both the Sabbath and the Sunday service are not the worship day to God, but only the Sabbath.
God has never taught us the Sunday service to receive His blessings at all.

Saturday worship(Sabbath) and Sunday worship are just one day apart, but the results are stark. The seventh-day Sabbath is a blessed day that God commands and gives us the blessing of eternal rest and sanctifies us, but Sunday is illegal in God's eyes to worship the sun god. Let's not worship on any day, but obey God's commandments to 'remember' the seventh day and keep it holy, so that we may receive the promise of the eternal kingdom of heaven.

In order to believe in God and be saved by God, first, absolute faith in God is required.
However, through the Bible, it is said that faith can become perfect only when it is accompanied by actions, not just words and attitude.
And it must be done in obedience, not according to our standards, but according to the standards God wants us to uphold.
Among the many commandments that contain God's promise of blessing, the seventh-day Sabbath is an important worship day that serves as a sign between God's people and God. If we want to give true worship to God and receive blessings, we must remember and keep the Sabbath day holy.

The seventh-day Sabbath that we observe now is a worship that God gives blessings like Abel's sacrifice. However, since Sunday worship is the same worship as Cain, in the end, we will not receive God's blessings.

Definitely Sabbathe is the commemoration day to make us remind of God's love and sacrifice so that we have to remember it by keeping it holy.

We must not follow man made teaching. Sabbath is God's regulation. When we worship on the Sabbath, we can receive salvation.

We must follow the word of God absolutely. We can receive the blessing from God when we keep the word of God.

Some people insist that the day of worship is not important. However, God said that God gives us the blessing on the Sabbath day, not the Sunday Worship. If the day of worship isn't important, God wouldn't say that. However, God clearly testified about the importance of the worship day. Therefore, we have to keep the Sabbath day on Saturdays!!

Salvation will be completed when we follow will of God. Then, which day we worship to God is God's will? on Saturday or Sunday?. To keeping Sabbath day on Saturday is God's will. This is definitely God's will.

Keeping the Sabbath day is the blessing that we are allowed to do.
