I urge you to read the earlier post before your read this one. (Relationship with God) No relationship can be enjoyed without constant communication.
Yesterday, I asked the Lord: How do I know Father that it is you who is speaking to me and not me speaking to myself? The Lord gave me a simple answer. He told me that everything He says to me will be in line with the Bible. The Lord will never say anything contrary to His Word.
That is one good reason to read the entire Bible. For it is written: In the beginning was the Word, and the Word was with God, and the Word was God. (John 1:1-2)
God is a Spirit (John 4:24) and He communicates with us by His Spirit. The Bible says: When He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come. He will glorify Me, for He will take of what is Mine and declare it to you. (John 16:13-14)
For the Spirit searches all things, yes, the deep things of God. For what man knows the things of a man except the spirit of the man which is in him? Even so no one knows the things of God except the Spirit of God. Now we have received, not the spirit of the world, but the Spirit who is from God, that we might know the things that have been freely given to us by God. (1 Corinthians 2:10-12)
Whenever God speaks to me He either makes me open the Bible and leads me to a scripture or He brings certain scriptures to my remembrance and explains them to me.
Through the Bible I have understood the the Nature of God and when we speak, I just know it is Him.
Jesus said: My sheep hear My voice, and I know them, and they follow Me. And I give them eternal life, and they shall never perish; neither shall anyone snatch them out of My hand. My Father, who has given them to Me, is greater than all; and no one is able to snatch them out of My Father’s hand. I and My Father are one.” (John 10:27-30)
