In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom he made the universe. The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.
Hebrews 1:1-3 (New International Version)
This GOD says: “I am GOD, the one and only. I don’t just talk to myself or mumble under my breath. … I work out in the open, saying what’s right, setting things right… I promise in my own name: Every word out of my mouth does what it says. I never take back what I say.” Isaiah 45:18-23 MSG
Today I want to credit Christy K. Robinson for referring me to the above verses and suggest that you refer to her blog for more on hearing God's voice.
Have a truly blessed day.
