Why Settle for Less?

Do most Christians believe that God has wonderful plans for them? If they do, why do they settle for less?

For example, they will take borrow money that will keep them from giving to God because they want something like a new car. If they believed God has wonderful plans, they would wait to see how God would provide. Often, He may not get them a new car but would put them in a position to see some greater plan in their lives. It may be that He will move them to the job that they always wanted which will provide the funds for a new car. Their inability to wait upon the Lord made them settle for less than what God has for them.

The unwillingness to wait upon the Lord has caused many a girl to marry a man who does not know the Lord. Her life is one of trying to change him. She struggles to show her sons that they should know the Lord. She is given miseries that the Lord never intended for her. She simply settled for less.

I think I can give the antithesis of Isaiah 40:31 for those who settle for less:

But they who don't wait for the Lord
shall lose their strength;
they will join the turkeys in their walks;
running will be too hard for them;
their weariness will cause them to faint often.

Don't settle for less. Wait on the Lord for His best.

 Isaiah 40:31 (ESV)
³¹ but they who wait for the Lord
shall renew their strength;
they shall mount up with wings like eagles;
they shall run and not be weary;
they shall walk and not faint.
