Can a person do God's will if they don't try and make new Christians? Can they glorify God? Jesus said, "He who is not with Me is against Me; and he who does not gather with Me, scatters," and, "Every branch in Me that does not bear fruit, He takes away...My Father is glorified by this, that you bear much fruit, and so prove to be My disciples."" (Luke 11:23; John 15:2;8)
Did you know that 1/0 is undefined, but it can almost be thought of as "approaching infinity?" That's because 1 is, in a strange way, basically infinitely greater than 0. The difference between 1 and 0 is HUGE! Making just ONE new Christian in your lifetime makes almost an infinite amount of difference.
Let's work with Jesus and prove to be His disciples, bringing God glory by adding new Christians to the Kingdom!
(OTOH, if we just tromp around where Jesus is going, but aren't doing what He's doing, we're more likely to trample things underfoot and scatter the harvest—NOT GOOD!)
"For the entire Law is fulfilled in in this one word: "You shall love your neighbor as yourself."—Gal 5:14
