What is life all about?

So many philosophies to answer the question: 
What is life all about?
The only true answer comes from reading the Bible!
Confess Jesus as Lord.
Be filled with His Holy Spirit,
Be led by that Spirit,
Serve God.
All else will "fall short of the glory" that He intends for us to accomplish in His name.
You may say: "I don't understand? What do you mean or how do you do this?"
Again, line 3 works well for the answer!
Reading is Feeding.
He, (His Word), is real food, real drink, so just read, This simple act will lead you to accomplish line 4-7.
My suggestion is is to start with the Gospel of John, then the epistles of John 1, 2, and 3. After that the Book of Acts. Reading these 5 books several times in a row will bring your spirit alive and answer a lot of questions that you may have from: "Who is Jesus, to how does the Holy Spirit come to you, and what does He do."
I guarantee that you will not cover these books many times (suggested 10 to start), before you will begin to have a Revelation of Jesus Christ.

I always start my reading with a simple prayer:
"Lord bless this reading with your wisdom and understanding, write it on my heart, and bring it to recall, in accordance with Your will, convenient for this day."
That will invite the Holy Spirit in to "guide you, and remind you of all that Jesus said and taught" so that we can "Glorify our Father in Heaven", as He did walking this earth.
The more you read Scripture, the more you "feed" on the Word of Life. The more you grow in Christ, and make yourself more valuable for the Masters use.
That's what "life is all about."
I challenge you to "test" this application for 30 days and see if there is anything said here that is false.
May the Lord lead and guide you, in Jesus name!
God bless and keep.
