Continue in Faith - 1 Timothy 2:15

[They shall be saved] if they continue in faith and charity and holiness with sobriety.

Here, Paul was speaking of women, but the advice applies to both men and women generally. The point I noted with this passage is the word "continue". It expresses a need to persevere. It is not a done deal once we have attained to a certain level of faith, but we must continue to keep it active and continue to grow. No matter how advanced we may be in our faith, there is still a need to exercise it and receive growth.
