In this world, not everything that happens is God’s will.
There are pains that happen that are contrary to the Will of God. For instance, in Exodus 20:14 God commands us to stay away from adultery, but many people go against this command. Why? It is because God gave every man a free will. This free will is a gift from God to all human beings.
Thou shalt not commit adultery. Exodus 20:14
Similarly, angels were given a free will by God to worship and honor Him. The essence of this free will is to show how much we love and respect God without compulsion. He is pleased when we willingly submit to Him. He is pleased when we obey Him without force, without anyone dictating for us, etc. Unlike some religion that practices their belief by forced indoctrination (sometimes to an extent of a gunpoint), Christians are given a free will to decide if to follow Jesus or not.
God is a God that is pleased on persons obeying Him with faith and free will irrespective of the surrounding temptations. So, whatever happens to a person cannot be concluded to be God’s will. It can possible be either will of the person or the will of the devil dwelling in the person. Bro Eli reflected to the story of Mary Magdalene who was possessed of seven demons to do the will of the devil. Meaning her past life was controlled by the devil until she encountered Jesus. God gave us our own free will and allows us to decide what we want for ourselves. Deuteronomy 30:19
Today I have given you the choice between life and death, between blessings and curses. Now I call on heaven and earth to witness the choice you make. Oh, that you would choose life, so that you and your descendants might live! source
Our liberty in the sight of our creator is for us to make our own choice. However, despite giving us a free will, He still gives us His concern (… choose life that ye may live).
Conclusively, not everything that happens is happening because God wants it to happen.
