You ever notice how many cars go by with Christian bumper stickers on them?
Seems like it is much easier to show our faith in God by bumper stickers and outward signs that it is by living our life under the power and guidance of the Holy Spirit.
When we accept Christ, we receive forgiveness for our sins, past, present and future. We are crucified with Christ, dead, buried and then raised up again as new creatures in Him. The Holy Spirit comes to live within us and God now sees us as holy and righteous because He sees Christ in us. It’s what is on the inside that counts.
Jesus told the Pharisees that the outside of their cups were clean, but inside they were full of dead men’s bones. Hopefully that isn’t the way a lot of us are.
Because of Christ and the Grace He provided, we are clean on the inside, holy and righteous in His sight. Not because of anything we did, but because of what He did. Jesus paid the price, we get the benefits.
There is nothing wrong with being excited about our faith in God and wanting to show it with bumper stickers and various outward things. The main thing is that we take up our cross daily, follow Jesus and allow the Holy Spirit to live in us so that the true qualities of Christ will shine out of us.
