Imagine going to the doctor because you feel unwell. Upon arriving, you demand he give you an in-depth blood test, an EKG test for your heart, and an MRI of your whole body.
God can do anything he wants, whenever he wants, and by whatever method he wants. So if God doesn’t want someone in your life, why wouldn’t he just remove them instantly rather than “trying” to remove them?
Since we know godly relationships glorify the Lord, we also know that Satan hates godly relationships; thus, he will seek to keep you away from “your person.”
Sometimes we equate another person’s choices as God’s will for us. But just because someone pursues you or expresses interest in you does not mean this is definitely the will of God for you to be with this person.
