I'm not going to be very legalistic here, because we as believers have liberty.

The faith that you have, have as your own conviction before God. Happy is he who does not condemn himself in what he approves. - Romans 14:22

Now the Lord is the Spirit. And where the Spirit of the Lord is, there is liberty. - 2 Corinthians 3:17

If your conscience bothers you about something, it is probably wrong.

As free people, do not use your liberty as a covering for evil, but live as servants of God. - 1 Peter 2:16

No one can serve two masters. For either he will hate the one and love the other, or else he will hold to the one and despise the other. You cannot serve God and money. - Matthew 6:24
