As all have rightly pointed out, if Jesus didn't know the day or the hour (but merely the season), then Mr. Camping is not on the Need-to-know-list. Secondly, no where any place in the scriptures (old or new) does it say “Naggeth your brother/sister into the Kingdom of Heaven.” You can pray that God sends the Holy Spirit to ready the ground and then sends the workers, but faith is a GIFT, folks. The signal graces outlined in Paul's letters are GIFTS which, when asked for, are freely given. Our job is to pray and live a joyous, commendable life to the point where others will want what we have. Then we get the happy job of telling them that it's free for the asking. No more, no less.
It is the Father's work, through His Holy Spirit (whom, by the way, I'm madly in love with), and I can happily say the affection is returned daily.
That is so funny. There are many who think it will work.
