They go to mission trips, they think they are saved.
They go to churches, they think they are saved.
They take part in services, they think they are saved.
They cry at concerts, they think they are saved.
They shout the name of the Lord, they think they are saved.
They give to the poor, they think they are saved.
They have fellowships, they think they are saved.
They attend seminaries, they think they are saved.
They become church leaders, they think they are saved.
They become preachers and pastors, they think they are saved.
Why are we saved? Because we are holy. How do we become holy? because we accepted Christ's death and resurrection as our atonement for our sins. How can we accept? By repentance. With this holiness, we serve the Lord.
So, why should I involve myself with these unconverted ministries, if God has cleansed me. Support them, for the glory of God, I will, with wisdom, but I should not bring the wrath of God upon me by indulging myself with their affairs.
