From the day you Become a Christian, you should Lay Aside your ambitions and plans.
You should NOT seek to be an outstanding person in your particular field.
As a Christian, you should have ONLY ONE ambition, to be Well-Pleasing to the Lord.
You should have NO OTHER ambition than This.
Any worldly future you might once have had is SMASHED FOREVER.
Now you must be Prepared to be one who Serves the Lord.
