and with all deception of wickedness for those who are being lost, because they didn't receive the love of the truth, that they might be saved.
The reason some did not receive the love of the truth and salvation is they were deceived. We see another contrast between truth, which is characteristic of God and his followers, and lying wonders (verse 9), which are characteristic of the antichrist and his followers. The truth refers to the gospel. People who reject the truth are also refusing to receive God and all He stands for. In rejecting the truth (gospel), they reject the church which is built upon the truth. Paul says, "But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth" (1 Timothy 3:15).
