From Abraham to Ananais, the Bible speaks of children of God answering the call of the Lord. When Moses asked God who it was that he should say sent him, God answered with I AM.
I AM has been the accepted name of God in the Jewish and Christian religions. There is a hymn that speaks to the great "I Am". God still calls on people everyday to do His will and we should be fervently seeking this call and answer with Here I AM!
Let God use you today and let us always be readily available to the Great I AM when he calls our name.
And that is the Whole truth, God Bless
and remember God always answers His kneemail.
