“What do you think? If a man has a hundred sheep and one of them goes astray, does he not leave the ninety-nine on the hills and go in search for the one which went astray?” Matthew 18.12
If he left the ninety-nine on the mountains, of course he made sure they were safe and guarded, but the one that went astray was in danger of falling on precipices. For the pastor, it is very valuable. Thus Jesus treats His people, protects them, leads them to the green pastures, which is His Word, and guides them with His Spirit. But if one of His people goes out into the world, He will surely use people and situations to bring him back to His Safe Sheep.
