A disposable Christian is a disciple of Jesus Christ that is in all things submitted to the will of God, desiring to be used for God's purpose, believing every pleasure of this life is but a glimpse of what will come, believing every pain is a memory fading fast, that this life is but a vapor, and the life to come is the unfiltered infinite glory of God himself.

Therefore, disposable Christians delight in Jesus Christ so much that they are compelled to engage people and love them, be equipped and equip others, and to exhort the entire body of Christ to be on mission with God in the Kingdom of God now.

"For whoever would save his life will lose it, but whoever loses his life for my sake and the gospel's will save it." ~ Jesus, Mark 8:35
