Prov. 3:5-6

It is so hard to wait. To wait for direction for your next step, particularly when that step is not so clear, when you've lost a job, for example. To wait for God to bring you a spouse when it seems everyone else has been given one. To wait for your kids to grow up, especially when they seem especially disobedient and/or needy. To wait for your finances to be more stable. To wait for God to make you noticeably more like Himself, particularly in those areas in which you fail again and again. To wait for life to get better. To wait for Christ to return.
Why does it sometime just seem like life is about waiting?
And why does the Bible say, to wait on the Lord?
Help me, God, to trust you, to do what I know you want me to do and to know that you will direct me.
Prov. 3:5-6
