There is no such thing as gluttony being a sin in the bible.
(Rom 3:23) For ALL have SINNED, and come short of the glory of God.
(Rom 5:8) But God commendeth his love toward us, in that, while we were yet SINNERS, Christ died for us.
Christ died for EVERY sin we have ever committed in our lives -- sin is sin whatever sin it is.
Have you believed Christ died for your sins so you could be forgiven by God and have the promise of eternal life ? (Acts 16:31, Eph 1:7, Col 1:14 & Tit 1:2)
There is NO other way to be saved and enter heaven without Jesus as your Saviour.
Something to think about.
Yes, some pastors like christians are overweight and physically out of shape but that is a personal responsibility for each person to deal with.
Some christians have bad eating and hygiene habits.
We can't all be perfect like these slick and smooth looking televangelists who give the impression they never get sick or tired !
It has no bearing on their salvation in Christ because that is a free gift from God when you believe the gospel (Rom 6:23 & Eph 2:8-9)
