For Jesus, handicaps were opportunities for God to display his power. It's in the Bible, John 9:2-3, TLB. " 'Master, His disciples asked Him, 'why was this man born blind? Was it a result of his own sins or those of his parents?' Neither, Jesus answered. 'But to demonstrate the power of God.'"
Our limitations are only temporary. It's in the Bible, I Corinthians 15:53, TLB. "For our earthly bodies, the ones we have now that can die, must be transformed into heavenly bodies that cannot perish but will live forever."
The handicapped will be healed. It's in the Bible, Isaiah 35:5-6, NIV. "Then will the eyes of the blind be opened and the ears of the deaf unstopped. Then will the lame leap like a deer, and the tongue of the dumb shout for joy."
