It's only normal for us to feel that way sometimes. But the best way to be sure it is God's voice is to do what they did in the Bible: fast and pray.
You can do this for just a few hours. I read one story where a man fasted and prayed by skipping just one meal and his friend was released from a mental institution after having been there for quite some time. So fasting and prayer is so powerful that even just a few hours of it can do miracles. Another thing that fasting and prayer does is that it shows diligence and sincerity about seeking God. There are some things that are only revealed to us as we seek God with greater dedication(Jo.2:12,13;Da.chpt 10; heb.11:6). Daniel had to fast and pray before an angel finally got a message through to him about when his people would be set free from foreign captivity; David had to fast and pray to find out why a famine lasted 3 stright years in his country what they had to do to be delivered from it; Jahoshaphat had to fast and pray before God delivered his nation from the combined attacked of three other nations; and Paul and Barnabas had to fast and pray before the Holy Spirit could reveal to them where and whom they were to go and minister to(Acts.13). It worked then; it will work now. Try it.

I'll be praying for you.

God bless you, Rami!

mrjt,
Thank you so much for your comments.
I will do this! Praise God for answering in His Way as He unfolds our lives perfectly and for brothers and sisters that uphold each other.
