Yes, because he does exist. Knowing God better can add purpose and meaning to your life. (Acts 17:26-28) The closer you draw to God, the more he will love and help you. (James 4:8) Ultimately, having accurate knowledge of God can lead to unending life.—John 17:3. You can believe in God as you come to know him.
Think of someone you know well, such as a close friend. How did that friendship develop? Likely you got to know that person’s name, personality, likes and dislikes, as well as what he or she has done and plans to do, and more. This is what drew you to that person—you learned about him or her.
The name matters to God himself. No one gave God his name; he chose it for himself. Jehovah declared: “This is my name forever, and this is how I am to be remembered from generation to generation.” (Exodus 3:15) In the Bible, God’s name occurs more often than any of his titles, such as Almighty, Father, Lord, or God, and more often than any other personal name, such as Abraham, Moses, David, or Jesus. What is more, it is Jehovah’s will that his name be known. The Bible states: “May people know that you, whose name is Jehovah, you alone are the Most High over all the earth.”—Psalm 83:18. The name matters to Jesus. In what has been called the Our Father or the Lord’s Prayer, Jesus taught his followers to petition God with the words: “Let your name be sanctified.” (Matthew 6:9) Jesus himself prayed to God: “Father, glorify your name.” (John 12:28) Jesus made glorifying God’s name a priority in his life, and for this reason he could say in prayer: “I have made your name known to them and will make it known.”—John 17:26. The Bible says at 1 John 4:8 “God is love.” For more information you can visit jw.org
