Faith and Holiness

One verse that is easily apparent through a bible study covering Hebrews is Heb 12:15, it shows that there are terms beyond faith in the New Testament.

Heb 12:14

Follow peace with all men, and holiness, without which no man shall see the Lord:

You see holiness after becoming a Christian is a term or condition of salvation. This entails leading a life that avoids profane actions such as blasphemy,fornication, or idolatry; and includes making peace for the purpose of sharing salvation. It involves being set apart for God's purpose.

Faith plus holiness is a New Covenant doctrine, not faith alone.

Compare Romans 6 where all of the following are systematically applied to salvation.

baptism Romans 6:1-4

faith with obedience  Romans 6:17-18

Holiness  Romans 6:22

As a matter of fact, holiness is directly connected to Christ's free gift and the gift conditionally follows it.

The two verses, being back to back, show that the gift of everlasting life is conditional upon holiness. 

ye have your fruit unto holiness, and the end everlasting life.

 but the gift of God is eternal life through Jesus Christ our Lord.

Holiness can be required even though salvation is a gift.

But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.

Rom 6:23

For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

 Even though free from sin in this life according to v.22, we must seek holiness to complete the gift of eternal life.

The free gift mentioned here is eternal life, Holiness in Romans 6:22 preceeds the free gift that will be given when Christ returns. The Holy Spirit through Paul demonstrates a clear order.

made free from sin

become servants of God

fruit unto holiness

the end everlasting life

Of course they could answer that it wouldn't be a free gift with a requirement of any kind, especially something as demanding as holiness, but the same argument would be true with a requirement of faith only, a faith requirement is still a requirement. So they would keep one requirement but deny another. Hypocrites I guess?

Rom 6:22
