Your question presupposes that God is a Trinity, Sangeetha, so we’ll start with that assumption. Theologians often distinguish between the ontological Trinity and the economic Trinity. The ontological Trinity concerns God as He is intrinsically, unrelated to creatures. The economic Trinity concerns God in relation to us, particularly the roles played by each person in the plan of salvation. In asking “why did God choose to reveal himself as God the Father, God the Son? Why didn’t He wish to be the mother, or the friend or any other relation with the second person of trinity?,” you seem to divorce the economic Trinity from the ontological Trinity, as though God could reveal Himself to be something incompatible with the way He really is.
According to the classical doctrine of the Trinity promulgated at the Council of Nicaea, God the Father eternally begets God the Son. This relation is sometimes called filiation, so that there is an intrinsic filial relationship between the first and second persons of the Trinity. So it is impossible for those persons to be related as mere friends, mates, colleagues, or siblings. The only question would be why the genders are not feminine rather than masculine: why not God the Mother or God the daughter? Given that the persons of the Trinity do not literally have a gender (since they are incorporeal), why are they revealed as masculine? The Bible says that men and women alike are created in the image of God, so any non-physical properties of masculinity and femininity which there might be must be alike comprised by God’s nature. Since God is neither male nor female, why does He reveal Himself as Father and Son?
