John 17:3
And this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent.
You cannot truly know God unless you truly know Christ Jesus.
Eternal life is not the strumming of harps while we lounge on clouds. Eternal life is knowing God, being with God, dwelling with God, and glorifying Him in all our thoughts, words, actions, and deeds!
The only way to know who God truly is, is to know Jesus Christ. For there is no other name under heaven, given among men, by which we must be saved.
There are other religions (Judaism, Islam, Mormonism) that believe they know God but still deny Christ. There is only one God, and He has revealed Himself in the Person of Christ Jesus, who is fully God and fully man. Since all other religions deny Christ Jesus, they deny God.
The goal of the Christian is to know God and to make Him known in every thought, word, action, and deed—all to the glory of God. We can only come to know God through His Son, who came according to the Father’s will, lived a perfect life, was crucified on a cross, placed in a tomb, raised on the third day, and ascended to the right hand of the Father, still fully God and fully man, and is our great High Priest before the throne of grace.
Acts 4:12, Hebrews 8:1
Father, help me to know You intimately and purposefully through Christ Jesus! Forgive me for how often I walk, talk, and act in unbelief rather than acknowledging Your sovereignty over all things. Help me to walk in accordance with Your Word, by the power of the Holy Spirit, through Christ Jesus, for Your glory. In Jesus’ name I ask this. Amen
