How Do Christians Avoid Walking in Error?
The study behind the episode. Pointed at the person who wants to sit a little longer with what was taught.

The Christian life is one of incredible accuracy, but it is not one without mistakes. There is really no need for mistakes. You do not leave yourself to error and hope for the best. You inoculate yourself ahead of the error, instead of doing damage control after it.
And you inoculate yourself with the Word of God only.
Two stories carry the whole teaching.
Each one shows the same thing from a different angle: how error moves in on a believer, and how God's word holds a life together.
The word focuses
The episode is built on one Greek distinction and one Greek concept. Both have their own word study, which you can read in full.
The main points.
Four points drawn from the two stories, in the order they land in the episode.
There is an infilling of wrong thoughts, and it is a gradual process.
Luke uses plēthō for the believers in Acts 4:31. Peter uses plēroō for what happened inside Ananias in Acts 5:3. One filling is a moment. The other is a state. Satan did not strike Ananias once. He saturated him slowly.
Get filled with the right thoughts. Acts 20:32 says the word is able to build you up, and "build you up" is itself a kind of filling.
The greatest promoters of the foolishness you could manifest are those around you.
Tobiah stood next to Sanballat and mocked the wall: "if a fox go up, he shall even break down their stone wall." Sapphira had, in the Amplified's wording, "full knowledge and complicity". The devil's inputs often arrive through the people closest to you.
Keep the right friends. Evil communication corrupts good manners.
Not being full of the Spirit leaves room for error.
If plēroō is saturation, then saturation leaves nothing uncovered. In Ananias there was room for a deception that had been building for a while, because the saturation of the Spirit was not there.
The Holy Ghost will lead you into truth, but you have to be full of Him. Perfectly in touch with Him.
For every good thing God wants to achieve, there is one input the devil will attempt to make.
In Acts, it was the first move of the Spirit towards shared financial giving. In Nehemiah, it was the first attempt at the wall after years. In both, the attack came from inside, not outside.
"The gates of hell shall not prevail" means it intends to. "Beware of dogs." You are not warned about dogs that are not nearby.
For your own study
- Where in my life would an honest look show a slow filling I have not noticed?
- Who are the people whose words settle into me most easily, and what are those words usually about?
- What is the first new thing God is starting in me, and what has turned up alongside it?
- Am I being saturated by the Word in a way that leaves no room for other voices?
