“Surely none of the men that came up out of Egypt... shall see the land which I sware... because they have not wholly followed Me: Save Caleb... and Joshua... for they have wholly followed Yahuah.”
Revelation:Outwardly people were following/obeying Yah, but inwardly their hearts were not with Him, and this ultimately would cost them their place in the Kingdom/Promised Land/Paradise.
Parallels:Matt 25:1-13 ~ the parable of the ten virgins
Matt 13:24-30 ~ the parable of the wheat and tares
Matt 7:22-23 ~ the workers of iniquity who did mighty works in His name
The above mentioned parables parallel the revelation in Numbers 32:11-12, in that they depict a people who outwardly appear to be christians, believers in Truth, and followers of the Way. These people have outward signs of conversion, and their works give an appearance of a status that does not match the true state of the secret inner workings of their hearts. Inwardly these people are not truly following Yah, and despite the show they put on, eventually they will be unmasked.
Conclusion:May we take heed, for outward obedience is not enough. It is possible to look very much like we are following the Messiah, when in fact our hearts are far from Him. Not everyone who obeys/follows after Yah will enter into His Kingdom, but like Caleb and Joshua only they who obey/follow in both their outward and inward lives will enter in.
