Romans 5:5 tells us that this great love of God is "shed abroad in our hearts by the Holy Ghost". Wow! Imagine the potential we have for loving people because His love fills our hearts. I am convinced that we have the capacity to love many more people than we think and the more we chose to love the greater that capacity becomes. It is like a couple with a growing family. They love the last child as much as the first.
That blesses me because the Bible says that Jesus is the "first born of many brethren" meaning we are born to the family of God. God loves us as much as His First Born!
Meditate on this for awhile and just see if you don't feel that love growing inside of you.
