The Lord does not call followers to a vague and purposeless life.
Every believer, once the Spirit indwells them upon belief, is infused with a gift used to build up the body of Christ, the Church. Some gifts are even a catalyst to leadership within the Church. Others are tendons and muscles and veins and even cells that unite and serve the body in immensely intricate and eternal ways.
In Pauls short, personal, obscure letter to Philemon, the runaway slave Onesimus may have been hard working, he may have been apathetic in his service to Philemon. Whatever the case, upon realizing his worth at salvation, that Jesus would die for a gentile slave, his awareness of living a life worthy of that Gospel brought about a powerful reconnection with his birth name - Onesimus, which means 'useful.'
The Divine Nature of God intersects with life in refreshing and awesome ways.
You and I do not have vague spiritual lives to live.
As the Spirit indwells us, He also infuses us with meaning and value. Because we are made in His image, we have purpose. There's something about meeting Jesus that awakens our souls to that reality.
...and the gifts of the Spirit are a wild overflow of the Kingdom of Heaven uncarnating us.
You and I are useful. Period.
Read Philemon - Romans 12 - 1 Corinthians 12
