Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates? (2 Corinthians 13:5)
Hopefully, you (or another person) have given yourself an honest, thorough evaluation on your spiritual vital signs.
You should have a good idea where you are strong, and where you are weak. This will tell you areas that you need to improve on. You may also decide that on some of these weak areas, that you will let someone else fill in when someone strong in these areas is needed. This is analogous to a football wide receiver who is weaker at blocking; when more blocking is needed on a play, the wide receiver will come off the field; and a player who is a better blocker will replace him.
Please remember that this is just a tool. After all, a tennis player who is thoroughly charted as far as where they are strong and where they are weak will probably still never win Wimbledon.
Evaluating your spiritual vital signs might not show you where you are going spiritually; however, it can show you where you are. If you are weak in a number of areas, you may want to look at and pray about two or three areas to improve, rather than try to improve all areas at once. Of course, if the Lord leads you in a different path, by all means you need to follow His leading.
