In verse 12 the word temptation could be used a few different ways. The word means a test. It could also mean a trial or it could mean temptation to sin, which the next verse seems to insinuate. If we are tempted to sin, we are not to blame God or the position we are in. Years ago a prominent Christian lady said that God told her to divorce her husband. That could not have been from God for in his Word we are told that God hates divorce. (Malachi 2:16 ESV)
The key verse14 phrase is "drawn away." We are moved from the place or position where we ought to be. Another key word is "lust." Something we want but shouldn't go after. The end of that road is death. We need not lust because God gives us all good gifts. Lust is a lack of contentment with the blessings God has given us. It is also a sign of ungratefulness.
What does it means that we might be a kind of first fruits? The key verse to me would be a "kind". If a man had a wheat field in the time of the law of Moses, he would take a handful of stalks to the priest. That is what my field of wheat is like. We need to be examples of what Christianity is like. Then people would be excited to come follow after Christ.
