The simple answer is the Lion of Judah - also know as Jesus Christ. I don't share my faith enough. Too many people, and this has been engrained in us culturally, believe in a weak, milksop Jesus. In the Bible Jesus is described as the Lion of Judah, and there is nothing weak about a full grown lion. The Bible also says that Jesus spoke with authority - unlike the religious leaders of his day.
The point is - I am bought and paid for with the sacrifice Jesus made on the cross. That doesn't make me perfect. None of us ever will be or can be, but we are covered by his blood. This old world is under a curse. We have a body of flesh and we have a soulish mind. It is our spirit that is eternal. When we accept Jesus as Lord and Savior, our spirit is born again through the Holy Spirit of God. The Holy Spirit of God is our comforter, our encourager and our teacher. Our flesh and our mind still bound by this world wants to sin. It is through the power of the Holy Spirit and growth in the Holy Spirit that makes us different people. Even the Apostle Paul claimed to not yet arrive. Despite our imperfections, we are still covered by the blood.
This World is counting down. When I do not know, but everyday is another day closer. Even the natural world groans under the weight of sin with earthquakes, tidal waves, hurricanes, and storms. One day Jesus will return and the Bible says he will not only make things right, but he will rule with a rod of iron. The Bible is built on promises of a savior and his return. We can claim those promises or reject them. Me personally? I want to quest after God.
