This concept is simple, but at the same time confusing to some people. Jesus spoke once to an educated man, a ruling council member in Jewish society, a Pharisee named Nicodemus. This man recognized That God was with Jesus, but Jesus told him in order to see the Kingdom of God, a man must be born again. Nicodemus did not understand at first. He thought Jesus meant be born from their mother gauin but Jesus said, "I tell you the truth, no one can enter the kingdom of God unless he is born of water and the Spirit. Flesh gives birth to flesh, but the Spirit gives birth to spirit." We are all born and we all die, but we choose when to die and when to truly live. All are faced with the choice, the blood of Jesus is enough to cover everybody who was ever alive or will be. Not everybody accepts. So many reject God's offer of salvation. We all choose our scond death, we can die to our flesh and live in spirit eternally or we can live in our flesh and die spiritually for eternity.
This is not a happy topic. It is sad and hard to understand, but Heaven and Hell are very real. And so is God. We who are saved, who have died to self, who daily carry their cross, who were crucified with Christ, are called to a higher purpose, to higher standards. No longer can we live as though we were members of the world. We are to be above reproach, to live with love, and faith and goodnes. To seek holy, righteous purity of flesh and spirit. In our DNA is flesh, sin, and ultimately death, but we receive a new, spiritual DNA when we receive our new life. The DNA of truth, love, and ultimately life.
In Ezekiel, God gives the prophet this vision:
The calling of the watchmen.
If you see danger and do not call out in warning and a man dies, his blood is on your hands.
If you see danger and do call out in warning and a man dies, his blood is not on your hands because you sounded warning.
This is true still, but under the new covenant with Christ we will not be condemned to Hell for not warning our friends, family, neighboors, and even enemies of the eternal danger, but it is our greatest calling. We are to speak the Truth and proclaim the Good News. We are to offer Life to those who are dead. When I say dead there, not the death of their flesh, because then it would be too late, but spiritually many are dead as they life in this world. They do not know the Truth, but they are accountable to be judged nonetheless. For Christians, the judgement is not of our sins, which God chooses not to see because of the lense of Jesus' blood, but of our fruit. He cares about what we do with the resources and gifts we are given.
In the Christian life, there are levels of committment we can work toward. ( I am trying to be cautious here, I am not saying that we can be saved by anything but faith, but our faith is made alive through our deeds and when we bare Christian fruit.) The first level is good. When we are good, it is just the simple transition from darkness to light. It is becoming a follower; simply accepting the offer. That is good.
The second level is better. Better is where a Christian starts to explore the Word, to pray, to live a loving life, to fellowship, but mostly there is not a full maturity. It is a stage of development in which the relationship between a human and God grows, but the person does not fully understand God's will and purpose in their life. This could include being discipled, attending church regularly and other similar things. They are on the right track, but there is work to be done. That is better than good.
Finally we come to best. The best level of Christianity, their life is one of love and obedience. They worship in spirit and truth. They abide richly in God. There is abundant and obvious fruit that anyone could see. They present themselves a living sacrifice, holy and pleasing to God, considering it only a reasonable act of service. They meditate on the book of the law, not letting it depart from their lips, being careful to do everything written in it. They delight themselves in the ways of the Lord. They have tamed their tongue. They are testifying in all the earth with power they receive from the Holy spirit. They are teaching and baptising and making disciples. They have recognized their own weakness and been made strong through Christ. They do not let grace abound, and do not live in continual sin. They do not conform to the patterns of the world, they are transformed by the renewing of their minds. They are not anxious about anything, they present their requests to God with prayer and petition, constantly praying, and feeling a peace which is not understandable by man. They are strong and courageous, they are not afraid. They are teachable and seek God's face and heart always. They are patient, kind; not envious, not boastful, not proud, not rude, not self-seeking, ot easily angered; do not hold grudges or keep score, do not delight in evil; always rejoice in truth, always protect, always trust, always hope, and aways perservere.
What I just described as best, it is impossible, but it is the goal. To make ourselves more like Jesus everyday. As Christians, we have to recognize our failures in order to grow. The Devil has no footholds if we do not try to hide in darkness. In the light, Satan has no power. Daily, we need to remember that God did not create us to work alone. As individuals we fail, as a community, in fellowship with one another and God, we can do all things. (Not that God cannot use a person alone, but more often he works through a group.) The truth of the matter, if we are striving to be like Christ, to better ourselves, to help each other, to do good always, and to live lives of Christian love, we will be the best Christians we can be. I am a human being, supernaturally redeemed, and if you are reading this, you could be too.
