Falling is an out of control experience. People who have lost control of their lives often have nightmares of falling. Love is a deliberate action of the will. As Gary Smalley puts it in his book, love is a decision. To love means deliberately to turn ourselves toward another, to give away something of yourself to someone else without regard for return.
Love bears all things, believes all things, hopes all things, endures all things.
Couples getting married intentionally decide and commit, for better or worse, in sickness and health to stick it out, loyalty, together, devoted and working for each other. Love the Lord your God, says Jesus. Do it with all your heart and with all your soul and with all your mind and with all your strength. Very simply put - these 4 are mentioned for emphasis. They show that the whole person is involved in this love thing.
