Thanks @barncat for the visit and your comment.
Here is my response.
Petitions {Prayers}are requests made to God concerning His promises and His will to the believers.! Thus if it is God's will that a believer be called home , a petition against death by the believer is against God's will, thus He will not honour such because He does not counter His will concerning a man.
Jesus Christ desired a reversal of God's will about his death, but He realized its impossibility , hence Jesus concluded " let Gods will be done"
This is why it is critical that we endeavor to pray aright, according to God's will, in tongues which we may not understand!
God Bless You sir!
