Those who think they know something still have a lot to learn.
But if they love God, they are known by God.
Now about eating food that was offered to false gods: We know that the false gods in this world don't really exist and that no god exists except the one God.
People may say that there are gods in heaven and on earth--many gods and many lords, as they would call them.
But for us, "There is only one God, the Father. Everything came from him, and we live for him. There is only one Lord, Jesus Christ. Everything came into being through him, and we live because of him."
But not everyone knows this. Some people are so used to worshiping false gods that they believe they are eating food offered to a false god. So they feel guilty because their conscience is weak.
Food will not affect our relationship with God. We are no worse off if we eat [that food] and no better off if we don't.
But be careful that by using your freedom you don't somehow make a believer who is weak in faith fall into sin.
For example, suppose someone with a weak conscience sees you, who have this knowledge, eating in the temple of a false god. Won't you be encouraging that person to eat food offered to a false god?
In that case, your knowledge is ruining a believer whose faith is weak, a believer for whom Christ died.
When you sin against other believers in this way and harm their weak consciences, you are sinning against Christ.
