The Word of God is full of descriptions of who God is. In fact, the very names of God in the Old Testament are descriptions of who He is. This is something we often miss in the translation. God is called the Lord God Almighty (El Shaddai). He is called The Most High God (El Elyon). He is called Jehovah-Raah (The Lord My Shepherd), Jehovah Rapha (The Lord That Heals), Jehovah Jireh (The Lord That Provides), Jehovah Shalom (The Lord is Peace) and so forth.
God's Word says tells us these things but... how do I know that God this is who God is. You could tell me I must accept it because God's Word says it. You might argue that is what faith is. You're right, however, while God wants us to have faith in His Word, He also wants us to be in relationship with Him. In other words, He does not want us to simply know about Him. He wants us to know Him. Is there a difference? You bet there is!
Here at CB, we read the blogs of many people. In many of these blogs, the person may share personal information about themselves. After reading their blog, do I know something about them? Yes, but do I know them? No. I do not know them... I simply know something about them. We do not have a relationship with one another other than we are both members here, I read something they wrote and perhaps they read something I wrote.
Then, there are bloggers here with whom I have interacted with on a more personal level. We have chatted together via the chatroom, emails, telephone and/or in person. I've received gifts from some of them as well as cards and perhaps letters. I have met some of these people face to face and have even stayed in the home of a couple of members on several occasions. I've had a member visit my me and my husband in our home.
In other words, I do not merely know of these people... I have come to actually know them. I have interacted with them and am in relationship with them.
The only way I am going to know that God is Jehovah-Raah is if I am placed in situations where I needed a shepherd. I cannot truly know that God is Jehovah Jireh unless I find myself without and God provides. I cannot know truly know that He will deliver me from the fire, meaning adversity, unless I am in the midst of the fire and He does so. I cannot know that He is Peace unless I experience uncertainty.
I know that God is all of the above things and so much more... not simply because I have read about it or because someone else told me it is true. I know these things because I have experienced them in my own life.
You O Lord, keep my lamp burning; my God turns my darkness into light. Ps. 18:28
Or, as one old lady said..."I know in my knower"!
