"And ye murmured in your tents, and said, Because the Lord hated us, he hath brought us forth out of the land of Egypt, to deliver us into the hand of the Amorites, to destroy us.
"Whither shall we go up? our brethren have discouraged our heart, saying, The people is greater and taller than we; the cities are great and walled up to heaven; and moreover we have seen the sons of the Anakims there." --Deuteronomy 1:27,28
The Israelites had wandered in the wilderness forty years and now the people are directed to take the land which the Lord their God had promised to their fathers. And we hear this response.
Many times God's people are led into situations where trust in God and forging ahead is the correct response, and yet the task seems impossible. Of course it is impossible in our human strength, but with God on our side it must be accomplished!
Oh, but the sons of the Anakim are in the land. We've no chance against such a foe. And again, we today face assignments that are daunting or difficulties that seem insurmountable. And of course they are in our own strength. But God is on our side. He will neither leave us nor forsake us. If it is God's will we will overcome. Invest your trust in the Maker and Master of the Universe!
When God gives you a mission, He will equip you for the task.
