God is limitless to the ways He can speak, i have had vissions from Him for other people when i have been praying for them.
I have also had REALLY strong feelings when praying for people (to the point that i would cry in compassion for the person without knowing anything about them or their situation) this is called 'Word of Knowledge' (a gift of the Holy Spirit) where the Holy Spirit gives you an insite into a situation. In my cases The Holy Spirit has shown me what i needed you need to pray for, for that person eg depression/loneliness...etc
I have heard from God through other people, things that i had prayed about would then come straight up in a conversation and it would bring the answer.
Also when i feel a great peace from God, eg. if i am trying to make a decision i get a real peace about one of the choices and that feels right and i know God has just opened my eyes and shown me the way that He wants me to go.
God has also given me a direct verse when i was praying and i ased Him something and i was badly needing an answer then and there and a verse poped in my head (i had no idea what it was going to say, i hadnt read it before) and it was EXACTLY the answer to the question.
Alot of the time when i go to church or read the Bible it is EXACTLY what is going on with me at that time and is just what i needed to hear from God.
My fiancee has litrally been knocked to the floor of his shower by Gods presents and God spoke into his mind (he could hear it in his mind, like when you think kinda), and it was stuff that he didnt want to hear (he was getting pulled up about somethings in his life style that were not pleasing to God and God told him to fix them).
I have been talking to other Christians about their probs and then God basically drops words in my mouth like more than word ...full speaches, like there is NO way i could think up the things that i have said, it was God literally using my mouth and me to speak out loud to that person. Along with that i just feel the presence of God on me and His Holy Spirit (i even shake (its not a bad shake its a good kind :O)) And then it stops just like that and i have nothing else to say even if i wanted to its like God had said what He wanted to and then that was it, i stop shaking and back to normal.
Also things can get confirmed by lots of different sources (Bible, people, church message, prayer etc etc) and this can all hapen in the space a a few days...you get the same verse come up a few times then some one else brings it up in a convo to you etc etc.
So as you can see there are SOOOOO many different ways that God speakes to us, dont worry if you dont feel like He is speaking to you just yet, for some people it takes longer than others (Baptism in the Holy Spirit can Help with hearing Him clearly, if you have any Q's about that feel free to ask/email me/go to the Charismatic forum or look to God for that one too

). All you need to do is seek God with all you are and He will guide you and speak to you in a way that you will hear Him and understand Him. Trust Him and get into His word and keep talking to Him because He hears every word that you speak to Him and He loves to spend time with you.
I am in no way trying to 'show off' the ways that God has spoken to me but just wanted to show you some of the many ways that He can, and thought it would be good to hear personal experiences.
You can also do word searches on
