The most important is to prepare you for eternity.
Great opportunities are often disguised as small acts of service.
But no one who is lost has lost one ounce of value to God. Even if you don't have a relationship with him, you have immense value to God.
Let your broken heart create an open heart
If your activities don't match your priorities, you are wasting your life.
You were created to add to life on earth, not just take from it. God wants you to give something back.
