Birth, the sign of Life; it is a symbol of new life, a new creation. If you want to see King Jesus, you must be born again. It is a must if you want to walk on this journey. Jesus said you must be born again. Every sincere Christian purifies his soul to rid it of the uncleanliness and the defilement of sin, which pollutes the soul. Whoever is seeking salvation, must be purified thru the truth of the gospel, for we are clean by his words. The word of God says at our best we are but filthy rags. Jesus said "except a man be born again". We must have a new life; birth is the beginning of life, so the walk must start here. Just as physical life begins at birth, so must our spiritual life begin with the birth of our spiritual man.
The old foundation has faults and short comings, it can't support the glory or the treasure of this new building. We must have a new nature, with new principles, with new affections and new aims. We must be born another, a different person than the first; like the birth of Israel from Jacob and Paul from Saul. We will have different traits, different desires, doing different things. all Christians are born again. The first birth was after the first man Adam, corrupt, born in sin and shaped in iniquity, born to die, lost in need of a savior. So we must under go a second birth, a spiritual birth to take on the nature of our adoptive Father.
Born again, changed from a dead soul into a life giving quickening spirit. Walking in the spirit and not giving way to the flesh as it has been crucified with Christ on the cross, as we now live in a resurrected body, a temple not made with hands, now we are a new creature in Christ, sons of the most high Gods.
