Revelation 1:8: I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.
Jesus is the Alpha and the Omega, the beginning and the end. He was in the beginning of creation with God, the Father and He will be at the ending of the world. He was there at the beginning of the book of Genesis and He is there in the last book of the Bible, Revelation. He is from everlasting to everlasting. He is God incarnate, the second in Trinity. There was nothing made in this world without Him. He is also referred to as the Author and the Finisher of our faith. He begins a good work in us and will also complete that which He has begun.
Our whole being spins around Him. We breathe and live in him. Since He is the beginning and the ending, whatever happens to us in our life will be taken care of by Him. There is nothing hidden from Him. He knows us from the beginning and He for sure does know what our ending will be like. As long as we are committed to commit our needs and cares to Him, there is nothing that should worry or upset us. He is the totality, the sum, and the substance of the both of the old and the new testaments. He will carry us through from the beginning to the end in this journey of life. He never leaves anything unfinished.
Stop fretting and look unto this great God who cares for you. He sure knows what you are going to be and where you will be in some time because He knows you from the start. If you want to have a super-duper ending, then commit your whole life in His hands.
