On the day that you meet God face to face is He going to know you? Have you read all about Him? Have you been personally introduced to Him, and recognize His voice when He speaks to you? Or will He hold up His hand and say, "Depart from me. I never knew you." Although this would be horrible, I wonder how many hold their spiritual hand up to God, and tell Him "no" everyday? They don't recognize His voice. They don't have a relationship with Him, so they turn away from Him like a child would a stranger. Some may be so hungry for attention, or help, they will turn to anyone...that's ok. He will not turn them away. But what about the arrogant ones that think they have all they need, or want, and God is not in that equation? He is just a distraction, or worse a reminder of what they are, what they have done, and what they have refused to accept.
On that day--"Judgement Day", I want to know the God of the Universe. I want to know my Maker and Creator. I want to know the one who gave His life for me. I may have never seen Him face to face but when I do...I will know Him, because when I see Him, I will be like Him, because I knew His voice, I studied His word, and I spent time in His presence. He was not stranger to me.
