Hi Quendi, I support totally the answer of discreetslave above, I would say the same. So if you have been baptized in the same way it is valid. I remember when I was baptized 1988 at age of 13, one of the questions befor baptism with the elders was from the Organization-book: What does it mean to be baptized in the name of Father and Son and holy spirit? So it had to be undertood to be approved for baptism. So I regarded and still regard that I was baptized in the name of the Father and the Son and the Holy Spirit, even though just befor baptism at the convention they asked two other questions.
And I defend the necessity of baptism, because Jesus told: Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit, ... (Mathew 28:19) And therefor Cornelius was baptized, eventhough he had already got the holy spirit. In Acts 10 we read: Then Peter responded: 47 “Can anyone forbid water so that these might not be baptized who have received the holy spirit even as we have?” 48 With that he commanded them to be baptized in the name of Jesus Christ.
And I see that you wish to become chosen by Good, or as we call it usually anointed. It is a good desire, actually Jehovah God has been since the first centry searching and inviting people to his heavenly kingdom. And he has not yet been able to get the full number of 144000 and therefor the heavenly hope is still open. And to me it seems that those who get anointed are more than usually God-minded people. Here are some scriptures showing what kind of persons are on the way to the Heavenly Kingdom. Jesus said: But from the days of John the Baptist until now the kingdom of the heavens is the goal toward which men press, and those pressing forward are seizing it. (Matthew 11:12) So as Jesus says, you have to be pressing forward. That means you should not let the "organization" hinder you to speak about the truth as they say: Be quiet and wait for Jehovah, and don't disturb us. And it is not only the jw-society which opposes the truth, but generally the whole world is against the truth.
And a scripture that shows that you have to be God-minded: James 2:5: Listen, my beloved brothers. God chose the ones who are poor respecting the world to be rich in faith and heirs of the kingdom, which he promised to those who love him, did he not?
So what I mean with God-minded, is that if you are God-minded you will strive to please God in your best way and you will love Him. This is important because Jehovah God responds to the love an individual has for him, just as the scripture above tells about those who are to be "heirs of the kingdom, which he promised to those who love him".
So Quendi, I hope this information is what you wished to hear. May God bless you.
