Remember the Lord and share the blessing to others

Deuteronomy 16:1-17
Three times a year all your men must appear before the Lord your God at the place he will choose: at the Feast of Unleavened bread, the Feast of weeks and the Feast of Tabernacles. No man should appear before the Lord empty handed.
Passover do not eat it with bread made with yeast, but seven days eat unleavened bread, the bread of affliction. Remember the time of your departure from Egypt. Sacrifice the Passover the evening, when the sun goes down on the anniversary of your departure from Egypt.  Roast it and eat it , then in the morning return to your tents.
Celebrate the Feast of Weeks to the Lord your God by giving a freewill offering in portion to the blessings the Lord our God has given you. Remember that you were slaves in Egypt.
Celebrate the Feast of Tabernacles for seven days after you have gathered the produce of your threshing floor and your wine press. Be joyful at your Feast seven days.For the Lord your God will bless you in all your harvest and in all the work of your hands, and joy will be complete.
Last two Feasts should celebrate with your sons, daughters, menservants, maidservants, the Levites in your towns and the aliens, the fatherless and the widows living among you.
Why?
Three times a year to remember the Lord your God is blessing you.
Passover means set Israelite free from the slavery. Feast of week and Feast of Tabernacles are joy and have mercy to all family and poor or aliens or fatherless or widows. Share the blessing of the Lord to others.
How?
Celebrate the Easter, Thanksgiving and Christmas three days should remember the blessing of the Lord has done on us and share the blessing with others, who need the Love of Lord also.
