Gen 26:1-4
There is a reason why God appeared to Isaac and there is a reason why He told him not to go down to Egypt: It is time for people to trust in God, rather than to rely upon what they see or what they have. The time is coming that those things will fail.

The Lord told me that the time of xenophobia is past, but that we still have a problem. The problem is that people do not trust in God anymore.
2 Chron 20:20
The only thing that will deliver us from our circumstances is not in what we have, what we see or what we hear, but only to have faith in the Living God. We should also believe in His prophets that He has sent to us. Whatever we are facing in our lives, we need to learn how to trust in God.
Ps 118:8-9
It is better to trust in God than to trust in man, because God knew that man will fail, but that His words will remain forever.
