People do not actually need to do any works for God to require it only the works God leads us to as it says we are saved not of ourselves lest any one boast for we are His workmanship yet if one does not do works that God enables one to do that He has shown then one is not a genuine Christian and can be called a wicked lazy servant because he does not really care for others and what Lord wants.
We should follow only bible and it seems it could be even the bible does not teach baptism and communion is required as it says we are not saved of works yet it would still be required to be saved on death atleast baptism and maybe communion too so one should do it but I do not know so it should be done incase and leave judgement to God if it is not required.
Some may think it is required to do to exercise faith in Him as He taught it that you put your faith through obedience to do it while you have opportunity incase you can die suddenly without opportunity to call on God so one should do it to be safe incase. Some say it is only baptism that is required and communion was symbolic to eat Him spiritually that it is a time to try to commune with Him and remember Him as Jesus said it is the Spirit which gives life the flesh profits nothing and said the words I speak to you are Spirit and life it could be but as one can not know one should do it and leave judgement to God.
I believe we must not trust in our works as if they are required they are only evidence that we have accepted Christ that we do not do to earn salvation or maintain it if you think you are being saved because of your own works to think God needs you to earn by always working but you need to walk always in works that you know Christ leads you to it is required to maintain salvation as it is not your works but it is proof you have accepted Christ and our heart should be changed to want to help those who have genuine need to be giving to those we know especially need our help and for our heart to truly be changed to want to help at times if we think others may need help not needing to give every time if not our help is especially needed but willing to help at times if it seems others may need help.
That does not mean you do not have to forsake all you have to not seek to be rich to be following Christ you need to surrender all you have to have given away all you had before what you do not need to only leave for family what they need later for them not being old enough to provide for themselves but only to work for daily bread seeking first kingdom and the Lord will provide needs to prosper according to what you need.
But one does not earn salvation by works that you are required to always be giving but not to trust in riches that you need to be rich to trust in yourself one is required to surrender his life to Jesus to not work to serve mammon but for kingdom to only seek and trust the Lord for one daily bread and to be willing to give if there is a need from you and to give sometimes even if you are not only one needed but to help.
So I believe salvation could only be in bible for Him to be only mediator as He said I am the way the truth and the life no one comes to the Father except through Me.
We should enter only by Him to ensure we are saved because it may be necessary to trust only in Him to be saved of grace and not of ourselves and leave judgement to others up to God and to ensure we are raptured if there is one if we are abiding in Him through His grace and not of ourselves having a living faith working out our salvation not for it to see that we are conformed to His will.
