What is "destiny"? In simple terms, destiny is God's purpose for your life. It is your appointed or ordained future. Destiny is what God has predetermined you to be and to become, in His divine will.
I get sad when I read of the many godly men and women in Scripture who missed their destiny. God chose a destined work or ministry for each of them - but they ended up aborting His plan. They started out right, moving for a while in the power of their calling. But in the end, they died in shame and ruin - missing God's destiny for their lives!
