19 But when Sanballat the Horonite and Tobiah the Ammonite servant and Geshem the Arab heard of it, they jeered at us and despised us and said, “What is this thing that you are doing? Are you rebelling against the king?” 20 Then I replied to them, “The God of heaven will make us prosper, and we his servants will arise and build, but you have no portion or right or claim in Jerusalem.” Nehemiah 2:20 ESV
Growing up we've thought about being dentists, lawyers, athletes, doctors, coaches, etc. Then at some point we get exposed to people that want to mock our ambitions and cheer for our failures. This is a cold world. At some point your lose those ambitions and goals. You start to have a seed of self doubt.
My question to you is ... WHO TOLD YOU? Who told you, you were too short, too tall, not smart enough, too big, too skinny? Who told you this? Who told you, you cannot make, you won't make it? Who told you you were too dark or too white? Who told you, you would be a failure?
The God of heaven, He will prosper us. The God we serve, and under whose protection we are, who will supply us with everything we want, and succeed this undertaking, in whose name we engage in it, and on. The God whom we depend on, will provide in spite of all opposition, difficulties, and discouragements. So do not care what man says to hinder your ambitions.
God for your dreams, but be WILLING to SUBMIT and TRUST in The Lord!
