A smile, a thank you and a genuine gratitude is what I see in the eyes of this man whose name I do not know. He is grateful not only for my prayer, but the fact that I noticed, that I took the time to recognize him and speak well of him. All I do is reflect on what my Heavenly Father has told me many times, that He loves me and really cares for me. I am at a location near the train and bus depot where all walks of life are moving from one place to another. People are on the go and trying to do what it takes to survive. The fact that I recognized them as a person, rather than one without value getting in the way of those who are busy living life, makes them feel good. I feel joy.
God invented this feeling of joy that for some reason makes us soar in our minds with fulfillment and a sense of significance. Our Heavenly Father has engaged our minds to be overwhelmed with satisfaction because of actions we have taken that have affected others in a way they feel loved. There is nothing like it. To have joy, to feel joy. It only comes by selfless helping of others.
In the Bible, the disciples of Jesus Christ returned from being out witnessing and ministering to people, helping them get delivered and set free from the bonds of the devil, and it says: "the seventy-two returned with joy, saying, "...Lord, even the devils are subject unto us through thy name!" (Luke 10:17). They were doing the will of God and setting them free.
Virtually all service to others done with the love of God results in joy. There might not be a specific Chapter and Verse on this, but this comes close: "Yea, and if I be offered upon the sacrifice and service of your faith, I joy, and rejoice with you all." (Philippians 2:17). Even when Jesus took on the ugly task of the cross, He endured it for the "joy that was set before Him." (Hebrews 12:2). When born again believers recognize who they are in Christ and lovingly walk out on it and serve others, this combination produces joy. To see people respond to the love of God in manifestation is so thrilling and heart satisfying.
Let's bless each others and especially those who may be down and out or not being recognized by our society. When they respond by a smile, realize you have touched a heart for God.
"...But are helpers of your joy: for by faith ye stand." (II Corinthians 1:24).
