1 John 4:4 (NKJV)
When shopping for a computer, tablet, or phone, one thing that you will notice is that the device is not just sitting in a display with a price on it and nothing else. Normally there are some details given about what is inside of the device, as far as things like the storage space and the type of camera. The majority of people who are interested in buying one of these devices never buy it just based on how the product looks, they would want to know what is on the inside, because that is what really matters.
When someone becomes a Christian, the Holy Spirit comes to live within them, they become the temple of the Holy Spirit (1 Corinthians 3:16). Whether someone feels like it or not, the Holy Spirit is there. In 1 John 4:4, the Apostle John referred to the Holy Spirit as the "greater" One. But, are we always aware of that? Do we realize what is inside of us as a follower of Jesus? Do we realize that the One in us is greater that he who is in the world, referring to the devil? Too often the answer is no, we are not aware of that fact.
Because we live in this natural world, we can become more aware of physical realities than we are of spiritual realities. We need to look inside and realize that God has given us a Helper who will teach us (John 14:26), One who will lead us into the truth (John 16:13), and the One who will lead us in life (Romans 8:14). We need to turn our focus from the external to the internal and recognize that the Greater One does indeed live in us, and He will help us, teach us, guide us into the truth, and lead us in life. We need to look inside and see what God has given us!
