Dear wanted, thanks for sharing the quranic verses but it will be good idea to explain a bit as well as to what islam means in the context of verses around these verses and in context of other related verses that are found elsewhere in the quran in their own places.
Word DEEN is used in quran in various meanings eg in AL FATIHA, YAUM ADDEEN. Or in AL FATHA 2nd last verse as a way of life.
So it is not a creed but a way of life that is ideal for living in this world ie the quran teaches us that islam is a way of life that if we live by will land us in blissful life in this very world.
So any way of life we live by that leads us into toublesome life is not islam and tat is why we are not in peace or security that we ought to have. This is why we must l;earn what islam really is so that e could follow it.
regards and all the best.
