And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
When the Bible speaks of knowing it refers not only to know someone but have an intimate relationship with that someone. In John 17:3, the Lord says that eternal life is to know God and Jesus Christ. Therefore, eternal life is to have an intimate relationship with God, which can only be achieved through the person of His Son Jesus Christ. Without an intimacy with God it is impossible to know Him. The longing of the Father is that every human being can relate to Him. In this relationship, we become His children and He becomes our Father.
Since the Old Testament God had expressed His desire to be known by humanity. Jeremiah 9:23-24 says: Thus says the Lord: “Let not the wise man glory in his wisdom, let not the mighty man glory in his might, nor let the rich man glory in his riches; but let him who glories glory in this, that he understands and knows Me, that I am the Lord, exercising lovingkindness, judgment, and righteousness in the earth. For in these I delight,” says the Lord. Knowing and understanding God is much more important than wisdom or riches.
Jesus is the one who makes known to God. John 1:18 says: No one has seen God at any time. The only begotten Son,[a] who is in the bosom of the Father, He has declared Him. Only through Jesus, through the eyes of faith, we can see the Father. In John 14:7 we read: If you had known Me, you would have known My Father also; and from now on you know Him and have seen Him. Knowing Jesus Christ, we can see and know God, because as Colossians 1:15 says: He is the image of the invisible God, the firstborn over all creation.
In all periods of human history there have been religious people, including our own time, which is apparently apathetic to spiritual things. However, the way in which the different religions try to attain divinity is flawed. Every religion invents its own rites and formulas to reach God. What any religious person is thinking is whether his or her traditions make him or her closer to God. The Bible says repeatedly that no one seeks God; therefore, religions never reach their goal.
Instead of religion, God has sought, since the creation of man, have a relationship with mankind. Unfortunately we have ourselves been guilty of breaking all ties with our Creator. Sinful humanity cannot relate to a holy God. There is not any religion that provides an appropriate mechanism to restore the lost relationship with God. The solution comes from the initiative of God Himself, who sent His Son Jesus Christ in order to make Him known and break down the barriers that separated us from Him.
John 3:17 tells us why God had to send His Son: For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. Jesus came to save the world, for us to know the Father, which He is His visible image. When we know God through His Son, we reach the true eternal life. Receive therefore welcome that came to rescue us from death and sin, Jesus Christ, our only guarantee of eternal life, our only way to the Father, because besides Him, nothing. The step is very simple: repent and turn to Him. Do it now! God bless you.
