Why didn't my prophetic word manifest?
It's impossible for God to lie,when a prophetic word is given and it don't appear to come to pass there could be a few factors.
1) Did you believe that it would come to pass?
2)were you expectant ?
3)Were you looking for it to happen on your terms?
4)Did you exercise faith
5)Could it be your attitude towards God or the giver of the word.
The list goes on and on bear in mind it's impossible for God to lie often we like things done our way and to match our understanding but we have to die to self and let God choose how he desire to bring the word to manifestation,in other words you needed to be open minded.God watches our attitudes very closely,many times men and women of God had spoken in the name of the Lord and people mocked them and scorned them and were still expecting the prophets reward.I have seen people who have done so complained when the given time had past that the prophetic word wasn't true but it was after the man/woman of God interceded and pleaded their case before the father that the break through came.Now this isn't to draw attention on flesh because Jesus is the giver of the word once it's from him but a few things really matter when given a prophet word.
Shalom and love
