My gift to the world would be LOVE. I do believe that love is always the answer.
"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.
Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away (...) what is in part disappears (...) And now these three remain: faith, hope and love. But the greatest of these is LOVE." 1 Corinthians 13:4-13
