What does it mean to be spiritual as a Christian?
Romans 8:1 “There is therefore now no condemnation to them which are in Christ Jesus who walk not after the flesh but after the Spirit”.
Romans 8:5 “For they that are after the flesh do mind the things of the flesh but they that are after the spirit, the things of the spirit.”
From the scripture above we can deduced that there are two types of Christians: the spiritual Christians and the carnal Christians.
The carnal Christians are those that walk after the flesh i.e. although they are saved, born-again, blood-washed, tongue talking yet they are controlled and influenced by the system of this world. They crave for the things of the world and its affinity more than the things of God.
While the spiritual Christians are those that walk after the spirit. They have been able to cut away from the affinity of the world and yielded their desires and passion completely to the things of the spirit. It is very possible for a Christian to be carnal when he/she is so attached to the way of life of this world and its affinity.
