If we must obey the commandments that God has given us, we can receive blessings.
The Sabbath and the Passover are the feasts that God has commanded to keep.
Those who observe Sunday worship and Christmas cannot receive blessings and ultimately cannot receive salvation.
This is because Sunday worship and Christmas are not commandments that God has commanded to keep.

God's people must keep God's law. God's blessings are promised in the New Covenant.

The new covenant is a valuable gift given by Elohim God through holy sacrifice.

Worship is a sign between God and God's people. As a children of God, We should be able to give thanks and praise to God through the worship time that God has allowed.

We must keep the worship service holy.
And believe in God the Father and Heavenly Jerusalem Mother to the end.

Amen! Let's worship God with giving eternal thanks to God who redeem us from the sin and death. When we remember who we are and what suffer that God endures for us, we can offer holy worship God with all our hearts, souls and minds.

Amen!
God gave us an opportunity to repent and return to heaven after we were expelled to this earth because of our sins.
As a way to return to heaven, God has commanded us to keep the feasts (worship).
It is really arrogant for us as sinners to change God's feasts at will.
Changing God's feasts is an act of ignoring God's love, and it is an act that leads to destruction again.
Let's keep the worship of God wholeheartedly with a heart of gratitude for the grace that God has bestowed upon us.

Worship is so important. God seeks people who worship in spirit and truth. Jesus showed how we should worship. Jesus showed when we should worship. It is the Sabbath. Jesus showed all examples. We must not keep the worship with our way but we must follow God's way. Let's worship God as Jesus showed on Sabbath day.
