The key to having faith for the Lost lies in your love for them. I always think, that could have been my child, my parent, my sister or brother. I always desire the best for my immediate family. You know God thinks this way continually. The closer you dwell in your heart to God, the more the love and eager yearning for the lost will develop.
Jeremiah 31:3
King James Bible
The LORD hath appeared of old unto me, saying, Yea, I have loved thee with an everlasting love: therefore with lovingkindness have I drawn thee.
