Glad you are curious of this subject because this is an area that truly changes one's life after conversion. I've come to know how wonderful it is to see a soul won to Christ, but it is far more amazing to witness a new believer growing in Christ. In Peter 3:18 Peter give an exhortation to grow in knowledge and grace of our Lord and Savior Jesus, why? because it is a precious asset for the sanctification of the believer. Disciples are physically following Christ because He is not physically present but the internal drive inside of the believer is living to follow Christs example and in doing so denying self and being sacrificial for the sake of His love to spread and his light to shine in a dark world. A disciple will study the scripture, obey the word, live a holistic life. Desiring to live a life pleasing to God by putting on the love, compassion and the eyes of the Lord. any objections or Amen's?
