It means not living in the spirit. To live carnally, you live in the world. Many of us get caught up in the world. We are lured into it by commercials, social media, films and the everyday world of work ~ paramount social reality. When you work for a company, a corporation, the government, or have your own business, you are often burdened with issues, tasks and decisions that draw you out of the spirit and hardened you in the carnal world. It is very stressful to live in both trying to blend these very opposite worlds especially given today's complex social reality with its global agenda and political liberal relativistic correctness which does not exist in sync with a Christian 'correctness'.
What to do? For the most part, I pray you have a supportive spouse, parents, neighbors, pastor,friends and Christian community. If you find yourself in an uncomfortable position regarding your faith and spirituality, then ask the Lord for guidance. But, first, ask if what you are being asked to do truly weighs on your heart as a Christian or is it just a matter of dealing with an issue that kind words will solve.
If it weighs on your heart, you will know it. You will feel the burden on your spirit as a yoke to bear and one that you feel weighing heavy on you as it goes against the teachings of Jesus Christ. In that situation, ask the Lord to take that yoke from you. If you don't see any change in the situation, then ask if you can pass the task, meeting, or travel assignment on to someone else with the promise that you would be more than happy to take on something else in its place. If there is agreement, you will know that the Lord was with you.
Remember ~ "Come to me all of you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn me; for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light." Matthew 11:28-30
By doing this, you will be able to live spiritually!
