It is being obedience for Christians to attend Church regularly. If you honour God by your obedience, God will bless you. Your Prayers requests will be more effective & will come true more easily.
One of God's 10 Commandments. "You keep a Sabbath Day free to worship God." Why keep a free Sabbath Day in a week? So that you can rest from works every 7th Day. Why worship every 7th Day? So that you will remember God & worship Him regularly enough?
Why need of Duty to worship God? Because God has done a lots for us Christians. We need to sing praises & worship thanking Him.
Every Church has an Altar worshipping God. When you go Sunday or Saturday Service, you worship at this Altar. At this Altar, you can worship God more connectedly & more loudly. Also, Churches premises are properties belonging to God. If you or your family members still do little sins, then your bedroom or home still belong to the satan. Praying not at God's Churches, but at homes still belonging to the satan, will be less effective. There will be more satanic influences & "noises". Which make your prayers have too much "noises" to be heard by God clearly.
Jesus Christ in Holy Bible speaks of Christians should "remain as a member of the Church Body". Can a hand be cut off from his main body? Of course not. The cut-off hand will die. Therefore, if christians are cut-off from the Church Body, these christians will die off.
Going to a good Church. You will definitely meet a good Pastor. You will receive good Guidances & Instructions which God directs to you through that good Pastor. A good Pastor is given formal Authority from Jesus Christ to do Salvation Prayers, Deliverance Prayers & other Prayers request. Good Pastors will do it more effectively, better than yourself (non-Pastor trained) or fellow c/Christians (non-Pastor trained).
When you attend a good Church. You will enjoy good Fellowship with fellow good Christians. You can confess sins to them. Ask them for guidances (if you are too shy to approach your good Pastor). You & fellow good Christians can pray together (if your good Pastor is too busy with you). And most importantly, when you in a good Church, you will meet opposite sex good Christians. Befriending these opposite friends good Christians is how God arranges you to get married. How does God arranges a marriage to you if you always stay alone at home & work.
Going to good Church Services regularly will renew your Christian Faith regularly. It is just like a battery. You need to plug into a Main Electricity Source to charge it, after some uses, as uses will drain the energies of the battery. Therefore living in a satanic Earth world, your christian faith will be drained by the satan. You need to plug into the Main Electricity Source (i.e. Christianity God) at the weekly good Church Services.
When your Christian Faith is strong, you do zero little sins, all your past sins including little sins are confessed, your Prayers requests to God become more effectively. As you will receive more Blessings from God for your Obedience.
