To serve God we must know Him, and His eternal truth. We must follow Christ’s eternal and unchanging teachings to enter eternity with Him in Heaven. He has told us:
"I am the way, and the truth, and the life. No man cometh to the Father, but by me." (John 14:6)
God is with us always in the Catholic Church, assuring that His truth is present throughout the ages. It is available if we seek it.
"Ask, and it shall be given you: seek, and you shall find: knock, and it shall be opened to you. For every one that asketh, receiveth: and he that seeketh, findeth: and to him that knocketh, it shall be opened." (Matt. 7:7-8)
Part of the way that we seek Christ is by learning His teachings. The Apostles and disciples of Christ stayed with Christ for years, listening to all that he had to say, learning from His example, His works, His life. Christ, Who is God, is infinite; the entirety of His wisdom and ways are incomprehensible. It cannot be contained within one book.
And while we seek God in an in-depth manner, we must learn from the Church, from Her Holy Fathers, from the teachings of the popes, so that we can see Christ’s truth through the mist and murkiness that obscures its light. Errors have been proposed throughout all time to divert us from God’s truth. This will not change. To truly find Christ’s truth is to find freedom.
"And you shall know the truth, and the truth shall make you free." (John 8:32)
Christ, God, is the truth, and our life; He is the beginning and the end; He is our eternal goal. We must seek Him to find Him.
