We should desire God's salvation through Jesus Christ instead of God's wrath for the wicked. We should rejoice when the unrighteous accept Christ, even when it's someone close who has wronged you.
The Bible teaches that all food is clean. It's not what we touch or eat that makes us unclean, but what is in our hearts.
When you hear or read that the Bible teaches something, or there is something debated about what the Bible teaches, pray for guidance from the Holy Spirit; read the whole section or story of the teaching verse; and if there some debate, get verses from both sides of the argument and test them against the full context in the Bible.
