Christians may engage in any aspect of life. They are pardoned for every sin, past, present and future. I get these responses from idiots that think Christ died for nothing. I ask them which sins are forgiven by the atoning sacrifice of Christ and which are not? They freeze in ignorance.
Each of us have not been given a new commandment, but old ones. Our problem is we do not believe God will punish us. How can we not know that a male is a male and a female is a female? Insanity. A debased mind,...a reprobate mind. The answers are written down in Scripture, yet we still wrestle with right and wrong. If you still wrestle with whether or not to return a lost wallet with the money still in it, You are NOT a Christian and your salvation is in doubt. Grace covers mistakes, NOT deliberate sin. Scripture says you will be beaten with many stripes.
Our hearts must be purged of unbelief and we need a healthy fear of God. If all you get is "God loves you" and "God gives you grace", you probably are in deep trouble with Him. He has promised us eternal life. Why all the arguing?
You still have unbelief.
If your church sanctions gay marriages or abortions, your church is teaching lies from Satan. It's not about living in the 21st century or evolving culture. It's a bout what God has already said. God doesn't change. When Jesus comes, don't let Him be ashamed of you. We all want to hear," Well done, good and faithful servant". The only way to that place is believe what God has told us. The sin part has been atoned for.
For the believer in Christ....ALL sins are forgiven.
