--- If they ( the father,the word and the Holy Ghost ) were deleted from the Bible because they were not found in the oldest manuscript.That means that someones added them to the Bible purposely to market for' trinity" or to show the legitimacy of trinity .I think there is no other justification for that according to my minor thought.Perhaps your point of view is smarter than mine.
--- The current versions says :
New international reader's version7 There are three that give witness about Jesus. 8 They are the Holy Spirit, the baptism of Jesus and his death. And the three of them agree

New international version
7 For there are three that testify: 8 the[a] Spirit, the water and the blood; and the three are in agreement.

New revised Standard version
7 There are three that testify:[b] 8 the Spirit and the water and the blood, and these three agree.

New American Standard Version
7 For there are three that testify: 8 [j]the Spirit and the water and the blood; and the three are [k]in agreement

2- You always say " God placed us where God wants us to be, " . This saying is not true .It is called in language " The justification with fate and destiny". The theif can say that phrase to justify the theft "God placed me where he wants me to be" " If he wanted me to be honest he would do that"Then he is a theif accoding to the will of God ( God forbid) Also the atheist and the polytheist or the infidel can say that " God placed me where he wants me to be".This is the will of Allah (God fobid ) . Allah does not satisfy infidelity or evil for his slaves. In the past some polytheist said that Justification and Allah did not accept their justification and considered them liars.
148. Those who give partners (to Allah. will say: "If Allah had wished, we should not have given partners to Him nor would Our fathers; nor should we have had any taboos." so did their ancestors argue falsely, until They tasted of Our Wrath. say: "Have ye any (certain) knowledge? if so, produce it before us. ye follow nothing but conjecture: ye do nothing but lie."(6/148)
-- Allah also says "7. If ye reject ((Allah)), truly Allah hath no need of you; but He liketh not blasphemy from His servants: if ye are grateful, He is pleased with you. no bearer of burdens can bear the burden of another. In the end, to your Lord is your return, when He will Tell you the truth of all that ye did (in This life). for He knoweth well all that is In (men's) hearts.(39/7) Thank you dear Pandora.
