"Whoever is not with me is against me, and whoever does not gather with me scatters." - Luke 11:23
On the field of play the team distinction is quite simple. There are those on one team and those who are not. On the field of battle the distinction is the same. There are those who are patriots and those who are not. Apart from horseshoes, there are very few situations in life where "almost" is accepted.
As Jesus points out, spiritual matters are the very same way. No one can be on both teams or in both armies at the same time. If you are not with the Lord, you have chosen to stand against Him. If you are not gathering for the kingdom, you have chosen to scatter. When it comes to eternity, "almost" doesn't exist.
The world in which you live would like to be "gray" and ride the fence my friend. But the Lord is looking for those who will choose Him above all else. It is so stated in Ezekiel 22:30, "I looked for a man among them who would build up the wall and stand before me in the gap on behalf of the land..." The Lord desires those who will stand in the gap with Him. All others are not almost, they are simple against Him. The choice is yours... but you have to choose.
