Message
The Bible says it expressly that in the last days, many will be deceived by false prophets (Matthew24:11).
Deception is when you present something that is fake with some attributes of the original, or you omit or remodel some truth into something completely different while ensuring that it still looks like the original. There are many Preachers today who doctor the truth to fit the message that they personally want passed without thinking about the consequences. What they don't know is that they have been recruited by the devil to spread wrong doctrines. 1 Timothy 4:1 says:
Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
If people depart from the true faith of the Lord because of your message, then you are one of those spreading the doctrine of the devil. Always tell the whole truth of the gospel of Jesus Christ. Don't tell your congregation that because Romans 8:1 says there is no condemnation for those who are in Christ once they answer the altar call to surrender their lives to Jesus, they can continue committing sins and still be on their way to heaven. Add the rest of that verse to your message. The complete verse says: "who walk not after the flesh, but after the Spirit".
1 John 3:6 says:
Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
Thus the first part of Romans 8:1 means that those who will not be condemned are those who are in Him. According to 1 John 3:6, those who are in Him don't sin and whoever sins has not even known Him at all. Don't lead people to hell with your fake doctrines. Don't tell them to disregard the Old testament and only pay attention to the New Testament when Jesus Christ clearly said that He did not come to abolish the law but to fulfil it (Matthew 5:17). Speak the whole truth to everyone you have the opportunity to preach the gospel to.
