'I know your works, that you are neither cold nor hot. I could wish you were cold or hot. So then, because you are lukewarm, and neither cold nor hot, I will vomit you out of my mouth.'Revelation 4 : 15 & 16
Christians run in danger of lukewarmness in God. When we are dull towards the things and the Spirit of God, God said, He will vomit us out.
Why do Christians turn lukewarm in their love for God?
'If anyone loves the world, the love of the Father is not in him.' 1 John
Many Christians turn lukewarm because of their love for the world and the things in the world. The things of the world, the lust of the flesh, the lust of the eyes and the pride of life, eventually turn their hearts away from God.
We Christians need to repent of our lukewarmness towards God. When we no longer desire the love of God, when we no longer love God with all our hearts, minds and strength. When we sadly replace God's unconditional love for selfish loves and gains.
