Well, if this question is approached from the perspective that God ultimately is man's creator and is ultimately in control of whether or not certain people will find us, then no, one is unable to design his own creation--creation in this sense would mean one's life pathway. However, I see an inherent flaw in this view of God's involvement with man with the belief of free will. If God gives man free will, then he has burdened humanity with the responsibility of finding Him. Though God may aid humanity in doing so, he cannot ultimately have power over whether or not humanity does. If he does, then free will no longer exists. And as a result, humanity is unable to design its own course of life, its creation.
