1 John 2: 13 I write unto you, fathers, because ye have known him that is from the beginning. I write unto you, young men, because ye have overcome the wicked one. I write unto you, little children, because ye have known the Father.
This verse is telling we know God as we grow in our faith and our ability to resist Satan. We start out as children and we have a basic awareness of God and we need to grow. Next as we grow older in our christian walk we are not mature yet but have a good sound doctrine. This makes us stronger against Satan and brings us closer to God. Finally we get to a point where we know enough about God that we can know for a surety that He will do what He promises. It is our job at this point to be the leaders of our church family as wells as our natural family. We never stop learning but at some point we have to start living and teaching the word and wisdom God has given us.
