When you're driving along a road and see a stop sign if you value you're vehicle and life you'll stop at the corner before proceeding. Let's apply this principle to the excuses you're making regarding being who GOD created you to be physically, spiritually, mentally and emotionally. Next time you need to make a decision that will push you closer to fulfilling the purpose GOD placed you on the earth STOP!
Don't give yourself an excuse. Examine all of your options and pray for GOD to remove the obstacles you can't remove and strength to remove the obstacles you can remove yourself. Place a demand on GOD's promise for your life and EXPECT him to empower you through HIS Holy Spirit living within you!
