Numbers 20:20 And he said, Thou shalt not go through. And Edom came out against him with much people, and with a strong hand. 21 Thus Edom refused to give Israel passage through his border.
[Patriarchs & Prophets pp 422>423] Armed bands of Edomites were already posted at the difficult passes, so that any peaceful advance in that direction was impossible, and the Hebrews were forbidden to resort to force. They must make the long journey around the land of Edom. Had the people, when brought into trial, trusted in God, the Captain of the Lord's host would have led them through Edom, and the fear of them would have rested upon the inhabitants of the land, so that, instead of manifesting hostility, they would have shown them favor.
But the Israelites did not act promptly upon God's word, and while they were complaining and murmuring, the golden opportunity passed. When they were at last ready to present their request to the king, it was refused. Ever since they left Egypt, Satan had been steadily at work to throw hindrances and temptations in their way, that they might not inherit Canaan. And by their own unbelief they had repeatedly opened the door for him to resist the purpose of God. It is important to believe God's word and act upon it promptly, while His angels are waiting to work for us.
Evil angels are ready to contest every step of advance. And when God's providence bids His children go forward, when He is ready to do great things for them, Satan tempts them to displease the Lord by hesitation and delay; he seeks to kindle a spirit of strife or to arouse murmuring or unbelief, and thus deprive them of the blessings that God desired to bestow. God's servants should be minutemen, ever ready to move as fast as His providence opens the way. And delay on their part gives time for Satan to work to defeat them.
Hebrews 6:11 And we desire that every one of you do shew the same diligence to the full assurance of hope unto the end: 12 That ye be not slothful, but followers of them who through faith and patience inherit the promises.
May God add His blessing to the study of His word. “Good night” and God bless!
