In basketball, when an opponent puts their hand to close to the hoop when a shot is being made , it is called goaltending. Sometimes we set goals for ourselves and we become our own opponent. We doubt ourselves and ultimately block ourselves from our own blessings.
Whatever God has purposes in you heart, you have to trust and believe that it won’t fail. There is no failure in God. You may face obstacles or disappointments, but press your way through. Keep making shots, change up your angle and approach until your goal is achieved. And let us not be weary in well doing: for in due season we shall reap, if we faint not. (Galatians 6:9 KJV)
