To answer that question would take far more than this blog or this blogger can write, especially in a days time. God is the Creator, the Redeemer, the King of all that is, and He is our Father, our Protector, our Healer, our Friend. God is all of these and our Teacher because since He is present in the three persons of the Trinity He can be all of these at the same time.
We learn through His Holy Word, the Bible, which was written at the prompting of the Holy Spirit. We are saved and sanctified by Him as well through the cleansing power of the Spirit which creates in us a new heart and purpose for our lives when we accept Jesus as our Savior. When we have taken on His Holiness, then we are able to come before God at any time for any reason, no matter how small or insignificant we may think it is.
Consider the names of God and all that they imply about Him and His holiness. All that He is and all that He has done for the universe and for our lives is done and has been done because He loves us. Each of us, not just collectively as a race on Earth, but each individual that has been born and those that will be born. The time is growing short though, so I would consider giving my life and heart to Him if I were in your place. He gives each of us the time and the opportunity to come to know Him, all that we have to do is believe in the grace that has been given, and in Jesus’ sacrifice for us.
That is it, that is all that is necessary for us to know Him because He already knows you.
