Back to the OP.
NO, a blood bought and spirit filled Son or daughter of God cannot possessed spiritually by any evil spirit, demon, etc
this is because a saved person is the temple of the Holy Ghost [See 2 Cor 6.14-16]
However, a blood bought and spirit filled Son or daughter of God can leave a door open and become oppressed mentally and emotionally by an evil spirit or demon, which could manifest physically at times.
An example of extreme mental/emotional demonic oppression that manifests phsycial outcome is, unforgiveness.
I have worked prayer lines where someone comes up for prayer and is bound by severe Rheumatoid Arthritis.
The Holy Ghost has revealed to me that the person harbors unforgiveness in their heart, that has turned into a root of bitterness. The unforgiveness has opened a door to the spirit of infirmity to take over the mind and body of the person.
I have witnessed as the person comes forward,and repents and forgives that someone and be radically, immediately healed and made whole and they keep it. Sadly, I have also witnessed those that prefer to not forgive the person and stay bound by the spirit of infirmity and usually have ended up dead. Both times the people were saved.
This is why renewing the mind is so vital for sons and daughters of God and a very heavily talked about topic in the NT.
