Trust God's plan for us.. If we lost something or someone remember that it is for our own good..
When we lost something it's a reminder that we should take care all the possession that we have so it will not loss again.
If money, think that may be someone needed it more than us.. at least we help them in some way..
If a person may be that person will be happy without us it will teach us to be strong and independent.
Sometimes God's wisdom is difficult to understand because it is not we want but remember God will give us what we needed just trust Him and everything will be okay..
