"By this all men will know that you are my disciples, if you love one another." NIV
"By this shall all men know that ye are my disciples, if ye have love one to another." KJV
God is love. His character is to be love and to love. If we have given our hearts and lives over to Him, we will take on His character and love will naturally flow out from us. This love will be a love that the world finds utterly impossible to exhibit as human beings because it does not take into account wrongs suffered nor does it judge any person. All people will know that we are God's children if we have this love coming from us at all times. Don't we all want to be known as His disciples?
Heavenly Father, how often have we disappointed You by not showing the love that should naturally come out of us that You have placed there. Forgive us Lord for letting you down and keeping others from seeking that love. Help us Lord to stay close to You so that Your character will begin to take over our own earthly and sinful nature and that others will recognize You through us. We pray in Jesus' name, Amen.
