When we are reconciled with God, we are not only forgiven for our sins and our previous ways of life, we now have a relationship with God and a good one at that. We do so through faith and following his ways and leaving the simlpe life behind. It is very necessary because it's the relationship you have with God. If you don't reconcile, you will not have a good relationship with God and you can't possibly let him be in control and you can't possibly follow his ways. Jesus life saves us in so many ways. When he walked this Earth, he brought God's teaching and fulfilled propheses from God. Today, Jesus carries out God's will. By accepting Jesus and what he has done for us, we are able to be close to God. Thus, being saved and reborn. Everyday, Jesus is with us, for all things in life. He is our teacher, comforter, protector, and savior.
