God promised the Israelites a Promised Land which would be flowing with milk and honey.
When they went to spy it out, they found that It truly flows with milk and honey. (Numbers 13:28)
However, it also had the following problems:
1. The people in their Promised Land were strong (Numbers 13:28)
2. The cities in their Promised Land were protected. (Numbers 13:28)
3. There were giants in their Promised Land. (Numbers 13:28)
4. Their Promised Land was surrounded by their enemies the Amalekites in the south, the Hittites, Jebusites and Amorites in the mountains and the Canaanites along the sea shore. (Numbers 13:29)
Therefore regardless of whether you have received a spouse, child, business, job or any other of the Promises of God, if it comes filled with problems, do not throw it away like the Israelites who cried all night and said, "Let us chose a leader and return to Egypt!" (Numbers 14:4) when they realized their Promised Land was land filled with problems.
To deal with the problems in your Promised Land, go back to the same God who gave it to you and ask Him how you shall deal with those problems because He knew they were there when He was giving them to you.
We know that God knew the Promised Land was surrounded by the enemies of the Israelites because He told Moses "The Amalekites and the Canaanites live in the valley". (Numbers 14:25)
Emulate the woman who was given the promise of a baby by Elisha when he prophesied over her saying, "About this time next year you shall have a son" (2 Kings 4:15) and at the appointed time, she gave birth to a boy.
This woman's Promised Son developed a problem one day when he was in the field with his father for he complained of a headache and died. His mother took him and placed him in a bed and then asked her husband for a young man and a donkey to take her to the Prophet of God Elisha who was at Mount Carmel. (2 Kings 4:20-25)
She wisely chose to go back to see Elisha because he was the one who had prophesied about getting a child so that he could tell her what she would about the problem that her Promised Son had developed. Elisha solved the problem of her Promised Son and he came back to life. (2 Kings 4:32-37)
So if the Promise you receive comes filled with problems or it develops problems along the way, go back to God Who gave it to you or the person who God used to give it to you so that they can tell you what you should do next.
