You are so correct, we must listen to the 'still small voice within', to hear God.
For a long time all I heard from God was, 'I love you',
then as I continued seeking to hear from God, I heard more from God as I sat in prayer listening to hear Gods voice within. If it is all good, you know it is from mother father God speaking to you.
Also I noticed when I am doing Gods will, things go easier, I get all green lights in traffic, or there is a parking space right in front of where I am going, or if I call someone, the phone connection is clear and the other person is there. Things go smoothly under Gods divine government. Every day when I wake up I say,'I am under Gods divine government',that starts the day off more harmoniously.
If I am not doing Gods will I notice I get a lot of red lights or cannot find the place I was trying to go to, or if I call someone I don't need to call, the line goes bad
or the person is not there, or it's buzy or the connection is bad, or there is no answer. This is God telling us to change our human will.
Thy will, not my will, is another prayer that can be said all thru the day.
