We can lie to God and to mankind. It is very common practice in every culture. We tell people what they want to hear, and many times we want to be perceived with a great response.
We need to be real in this life. We should not be what we are not.
God loves the honest heart. Many people will go to church but their heart is not following the Lord. God see everything in everyone lives. The person needs to ask God to have a new desire so they can follow the Lord.
There is nothing wrong with admitting that we all sin. And we need help from the Lord.
If you are a believer then be obedient to the Lord. The Lord delights in the people that have a sincere heart towards him.
We need to respect other people. We need to be honest with people. If lying is a common practice then people can't trust the person. If a person follow Jesus but have a lying problem then their witness is not great. They need to be content in the position that the Lord has given to them.
If you want a honest heart then you need to accept Jesus. The cross of Jesus brings peace to the human soul. It is the bridge between man and God. We are separated from God because we are sinners. The cross of Jesus history explains the perfect man taking place of the guilty man. Have you receive the gift of pardon?
