That is everywhere found in the NT, the primary mark being sanctification/holiness.
"It is God's will that you
be sanctified. . ." (
1 Thessalonians 4:3)
". . .
be holy in all you do; for it is written: 'Be holy, because I am holy--
Leviticus 11:44-45.' "
(
1 Peter 1:15-16)
". . .called
to be holy" (
1 Corinthians 1:2)
. . .slaves to sin which leads to death. . .slaves to obedience which
leads to righteousness."
(
Romans 6:16)
"Just as you used to offer parts of your body in slavery to impurity, so now
offer your body in slavery to righteousness
leading to holiness." (
Romans 6:19)
Now that you have. . .become slaves to God, the benefit you reap
leads to holiness. (
Romans 6:22)
". . .let us
purify ourselves from everthing that contaminates body and spirit,
perfecting (completing)
holiness out of reverence for God. (
2 Corinthians 7:1)
In addition to
being declared sanctified/holy through faith in Christ's atoning death on the cross (i.e.,
justification),
the NT likewise teaches
being made sanctified/holy by the work of the Holy Spirit in the
lives of believers (i.e., process of
sanctification), through obedience in the Holy Spirit.
The NT presents
two kinds of righteousness/sanctification/holiness:
righteousness of justification (
positional--right
standing with God's justice--not guilty, righteous, sanctified) and
righteousness of sanctification (
progressive--a
process of growth in sancification/holiness).
We are everywhere in the NT commanded to
engage in the
action of a
process of holiness/sanctification in our
lives.
"Without holiness, no one will see the Lord." (
Hebrews 12:14)
