Before his gentle readers go all Luther on his keister, let this Aardvark say that he is not giving a pass to things like homosexuality, adultery, or dealing from the bottom of the deck. Here is the baseline from which this discussion proceeds:
Matthew 28:18-20, "And Jesus came and spake unto them, saying, All authority is given unto me in heaven and in earth. Go ye therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen."
As a rule, the church at the beginning of the twenty-first century seems to have, errrr, relaxed somewhat from Jesus' requirements of discipling and baptism. When the disciple finally confesses Christ, today one is more likely to hear "When's the next potluck?" (or "pot-bless" for the more superstitious amongst us) than to hear echoes of First century faith:
"...See, here is water; what prevents me from being baptized? (Acts 8:36)"
The testimony of the New Testament is clear.
God expects change.
God commands change.
God enables change.
1 Corinthians 6:9-11, "Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God."
Note this: "And such WERE some of you..."
The person given over to sin is not given a pass...discipleship inevitably pins the tail to one's donkey and demands change. However, one CANNOT submit to discipleship until one is a DISCIPLE.
If we present the life-changing truth of the Gospel, according to the New Testament pattern, then we can begin again to see New Testament results. Nothing else will work.
