Matthew 21:43-44 I tell you, the Kingdom of God will be taken away from you and given to a nation that will produce the proper fruit.
Jesus was at the temple talking to the leading priest and the elders who were trying to trip Him up. What I get from this verse and how it applies to us today is this...It doesn't matter how much we know, it doesn't matter if we can quote the Bible word for word. It does not matter if we grace the doors of the church each time it is open if we don't show love...if we don't produce the fruits of the Spirit which are love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control (Galatians 5:22) these are the things that come with a truly changed life. God knows when we do it to brag about it and when we do it because we love Him... people will know too by our love.
One example of this in today's world is a person that goes to church on Sunday morning.... then out to eat... then they treat the sweet kind waitress with contempt because she was working on Sunday and not going to church. They have been to Church but don't show love, they don't show the fruits of Spirit. The waitress on the other hand has been nothing but loving and kind, gentle and self controlled, but has not been to Church. If Jesus came back and could only take one person back with Him to heaven who do you think he would take?
We need to always act in a way that shows the fruits of the spirit.. we need to walk in love! God is love and if God is in our lives love with be in our lives. When we find ourselves not acting in ways that show love that is a warning sign that we are stepping away from God, even if we are in Church on Sunday mornings. It is not our Sunday morning clothes that prove we are a child of God, it is our actions! As the song says "They will know that we are Christians by our love, by our love. They will know that we are Christians by our love."
