"That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked at and our hands have touched—this we proclaim concerning the Word of life."
You really need to take a step back to enjoy the full enormity of this sentence.
That which is from the beginning is God. Not any god, but the Triune Creator God, the Father, Son and the Holy Spirit who was, is and is to come. He is the eternal one and the basis upon which all theing draw their being. He IS by definition and cannot NOT BE. He is the great "I AM", unchanging and unfathomable and untouched by time. However...
This creator God speaks to us so that we might hear him. Christ appears to us so that we might see him. But this is standard fare as religions go. They all have their own mystical experiences and visions and voices from the beyond. But what is unthinkable is that we have touched Him. We touched the fabric of all being. At one point , our God was made manifest on Earth and we could physically touch his hands and kiss his cheek and feel comforted by his embrace. We have touched the Word of life because he has reached out and touched us first so that we might live again and live eternally in fellowship with him and each other so that our joy may be complete. Who is like the LORD?
