I came across a quote which answers that question and may give you some insight into why I do whatever I do:
Our calling is to enjoy God as well as glorify Him. Real fulfillment relates to the purpose for which we were made, to be in reference to God, to be in personal relationship with Him, to be fulfilled by Him, and thus to have an affirmation of life. Christianity should never give any onlooker the right to conclude that Christianity believes in the negation of life. Christianity is able to make a real affirmation because we affirm that it is possible to be in personal relationship to the personal God who is there and who is the final environment of all He created. All else but God is dependent, but being in the image of God, man can be in personal relationship to that which is ultimate and has always been. We can be fulfilled in the highest level of our personality and in all the parts and portions of life… There is nothing Platonic in Christianity… The whole man is to be fulfilled; there is to be an affirmation of life that is filled with joy.
Francis A. Schaeffer

So, I suppose I blog because it brings me joy in affirming life through writing!
Why do you do, what you do?
I hope you will enjoy God by enjoying the purpose for which you were made — to bear His image and do the kinds of things that He does.
By His grace, together, we’ll get a lot done.
