If you have read my previous post (if you haven't then you should, or this one won't make much sense!!!), and are in a similar position to me - in that you are trying to conceive, why not consider praying and asking the Lord to speak to you - or to speak to a friend on your behalf - about your desire for a child. If you are going to ask about a friend, it needs to be a genuine friend who is in a relationship with God. Someone who you can trust, who you know won't just tell you what you want to hear, but who will be able to be real with you about what God has said to them.
I've had "words" spoken over me before, but as I didn't really know the person, or didn't really know where they were coming from in their walk with the Lord, I didn't really accept what they said. For example, someone told me toward the end of last year, that Bubba would be coming sooner than expected. I think the "word" came from their embarrassment at thinking I was pregnant because of the fat on my belly, rather than it being a genuine word from the Lord.
When it comes to prophecies, it is important we are able to test everything against the Word of God. I know my friend has a great relationship with the Lord. I know she has exercised her gift of prophecy in the past, and I know that - like me - she tends to have dreams from God. This is why I know I am able to accept the message she sent to me, and add it to what the Lord spoke to me through Hubby on that same day.
When we open ourselves to the Lord, He is more than willing to demonstrate His love for us and His desire to encourage us. Don't be afraid - let God gently lead you on this journey of faith and hope.
