The Word of God is the sustaining spirit that strengthens our faith in God. For our faith to be strengthened and to be sustained, we need to study the Bible. We read the Bible everyday and meditate on it. The word of God that we are reading from the Bible it the ingredients which gives life to our spirit. Without the world is God we cannot be sustained spiritually. The food that gives life to our faith is what we are learning from God's Word.
Remember that the Bible says that we cannot live by bread alone. That is when we eat food we give life to our body. But the life that we are receiving from what we are eating physically is not enough to preserve us. We need to eat from the spiritual food. This spiritual food is the one that gives us life and makes our faith in God to be strengthened.
For our own children to be taught of our religion, we must teach them the word of God from the Bible. To pass faith unto our children, we must pass the word of God unto them. We must teach them the things of God. It is the word of God that upholds our own faith. So, our children can only be strengthened in the faith by the word of God also. We should encourage our children with the words of God. Constant Bible study and fellowship can help to build the faith of our children. We should bring our children to come and learn the Word of God when the doctrines are being taught.
