Dusty idea is we have to keep gaining knowledge, seek to save that which is lost and become more spiritual.
There is a thought process that says just as soon as we have repented, confessed Him before men and contacted the blood of Christ through baptism, we're "good to go". At that exact moment we may be, but being spiritual isn't something we can gain from a static position.
1 Corinthians 3:1 - Brothers and sisters, I could not address you as people who live by the Spirit but as people who are still worldly—mere infants in Christ.(ESV)
You mean when you become a Christian you're still worldly, carnal? According to the apostle Paul we've just started the spiritual learning experience. We have the rest of our lives, however short or long that is, to strive to become Christ-like. Since we can't ever be perfect then the striving is the key it seems. If you were baptized and the blood of Jesus cleansed you and you fell into the "satisfied" category since that point in time, is that striving? If you haven't advanced in working for the Lord since that time, it's time to start to becoming a more mature Christian.
Back to our verse, Paul is addressing people that should have already been on the meat of the word instead of the milk. They were still mere infants and had probably been in the Lord's church for years. Does that describe you?
Ecclesiastes 12:13 - The end of the matter; all has been heard. Fear God and keep his commandments, for this is the whole duty of man. (ESV)
Luke 19:10 - For the Son of Man came to seek and to save the lost.(ESV)
If we're to obey God and emulate Christ, we're gonna have to seek to save the lost. About to make my politically minded friends and brethren upset probably. Seeking to save the lost governor's seat in your state doesn't come under this heading. Politics generally causes strife even among brothers and sisters in Christ. Less time on the political trail and more time finding people lost without hope in a dying world, that will accept the word. You know God didn't ask us to be soil analysts, just sow the seed. In the parable of the sower, he sowed everywhere. The sower didn't check the ground first. He just sowed the seed, it was up to the ground to allow the seed to grow. Threw that in for free.
