Hello Habib
I have noticed that you have asked several questions about the Trinity and therefore I felt I would like to respond to this. The way you descibe it, is not very accurate. I would therefore ask if you could take the time to read this explanation.
"Trinity" is a term that is not found in the Bible but a word used to describe what is apparent about God in the Scriptures. The Bible clearly speaks of God the Father, God the Son (Jesus Christ), and God the Holy Spirit...and also clearly presents that there is only one God. Thus the term: "Tri" meaning three, and "Unity" meaning one, Tri+Unity = Trinity. It is a way of acknowledging what the Bible reveals to us about God, that God is yet three "Persons" who have the same essence of deity.
Some have tried to give human illustrations for the Trinity, such as H2O being water, ice and steam (all different forms, but all are H2O). Another illustration is an egg having a shell, egg yolk and egg white, but this egg illustration shows that there would be "parts" to God, which isn't the case.
God the Son (Jesus) is fully, completely God. God the Father is fully, completely God. And God the Holy Spirit is fully, completely God. Yet there is only one God. In our world, with our limited human experience, it's tough to understand the Trinity. But from the beginning we see God this way in Scripture. Notice the plural pronouns "us" and "our" in Genesis 1:26 -- Then God said, "Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground."
Though not a complete list, here is some other Scripture that shows God is one, in Trinity:
"Hear, O Israel! The LORD is our God, the LORD is one!" (Deut. 6:4)
"I am the LORD, and there is no other; Besides Me there is no God." (Isa. 45:5)
There is no God but one. (1Cor. 8:4)
And after being baptized, Jesus went up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove, and coming upon Him, and behold, a voice out of the heavens, saying, "This is My beloved Son, in whom I am well-pleased." (Matt. 3:16-17)
"Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit." (Matt. 28:19)
Jesus said: "I and the Father are one." (John 10:30)
"He who has seen Me has seen the Father." (John 14:9)
"He who beholds Me beholds the One who sent Me." (John 12:45)
If anyone does not have the Spirit of Christ, he does not belong to Him. (Rom. 8:9)
[Jesus speaking to His disciples] "And I will ask the Father, and He will give you another Helper, that He may be with you forever; the Spirit of truth, whom the world cannot receive, because it does not behold Him or know Him, but you know Him because He abides with you, and will be in you." ... "If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him, and make Our abode with him." (John 14:16-17, 23)
In response to your other question. I believe that it is wise to pray to the God of Abraham, Isaac and Jacob. Only he can answer your question honestly. None of us can truthfully answer you, for we are not God. If you sincerely and humbly call out to God and seek him with all of your heart, he will hear you. If you love Jesus too, then ask him what the truth is.
P.S Salvation is offered to anyone who believes who Jesus was. That he willingly and in love, chose to suffer and die on the cross for the atonement of their sins,(paid their debt). If they believe that Jesus is not dead, but that he was resurrected and ascended into heaven. If they turn their back on their old sinful life, confess their sins, repent and finally trust, obey and follow Jesus in their lives, then they shall receive salvation. I can only recommend that you read the gospels in the New Testament for yourself. Asking questions on here, you will get various answers. Just as there are devout Muslim's, there are also some who are less devout. It is the same with Christian's. I believe it is important to educate and understand the scripture for yourself, so that you can read the words of Jesus for yourself.
God bless.
