Be spiritual.

I Corinthians 3:1
And I, brethren, could not speak to you as to spiritual people but as to carnal, as to babes in Christ.

The world we live in is a spiritual world. Hebrews 11.3 says the visible is made out of the invisible. God is a spirit and He created all matter.

Not many believe this because spiritual things are not obvious to the five physical senses. Think about YOU. You are a spirit, you have a soul and you live in a body. Your body is the only part that's visible and hence most people conclude that humans are just bodies and once they are dead, everything is over. You are not a body, you live in a body. You are a spirit and you possess a soul. Being spiritual means to have a spiritual mindset, to be spirit conscious and to see life from a spiritual perspective. There are two kinds of believers, carnal believers, who are also called babes in Christ and then there are spiritual believers, who are the mature ones. God desires each of his children to be spiritual so that we can fully enjoy his blessings. Spiritual believers give the word first and final place in their lives. They are serious about the things of God and consistently work on their spiritual development. It is imperative for you to be spiritual if you desire to fulfill your God given assignment and if you desire to hear the Lord say, Well done, good and faithful servant. Only the spiritual ones can finish their course and successfully fight the good fight of faith.

Friend, make a decision to grow up in the things of God because there are outstanding things to do and enjoy for the mature ones. Growing in the Lord has nothing to do with your age. It has do with your hunger for God and his kingdom and your willingness to do whatever the Lord says. In these last days, the spiritual ones will be used by God to show forth his glorious power to all the nations of the world. Participate. Be spiritual.
