It means why do we exist? What is the reason you are here? Why is there something rather than nothing?
In order: don't know, don't know, and don't know. Without knowing these answers, it's amazing I find my way to work every day! Okay, so what are your answers?
That is the point, you don't know why you exist and you can't know unless God has revealed to you why we exist. So, you can function quite nicely in the world but have no idea why you are here. Will relativism and subjectivity give you the answers? What is concrete about that? If you believe no one can know why we exist then I believe it is because you do not believe in God and He has not revealed Himself to you personally, in a mindful way and in a relational way that He continually confirms His identity. Again, the Christian has what is NECESSARY for certainty. God's existence and revelation would grant that. That would be an all-knowing God revealing to us that which is certain, for He cannot lie. Now you can disagree that the Christian can have absolute certainty, just like Salixes (Post 82) but again I have certainty, as have many others down through the corridor of time. Of course, you can question my sanity or think I am delusional but then I would ask you have you experienced a relationship with God or are you speaking outside such context?
We know that God does not hear sinners; but if anyone is God-fearing and does His will, He hears him.
What is His will? To know Jesus who has borne our sins in whose righteousness we stand before God. So how we achieve that will is not by our own works (what we do) but through the works of Jesus.
Therefore they said to Him, “What shall we do, so that we may work the works of God?”
Jesus answered and said to them, “This is the work of God, that you believe in Him whom He has sent.”
For this is the will of My Father, that everyone who beholds the Son and believes in Him will have eternal life, and I Myself will raise him up on the last day.”
So, the knowledge of God comes through His Son. That knowledge comes through belief in that Son and in everything He has done.
[ Oneness with the Father ] If you had known Me, you would have known My Father also; from now on you know Him, and have seen Him.”
This is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent.
Do you really think that worldly knowledge is wise?
1 Corinthians 1:20-24 (NASB)
20 Where is the wise man? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? 21 For since in the wisdom of God the world through its wisdom did not come to know God, God was well-pleased through the foolishness of the message preached to save those who believe. 22 For indeed Jews ask for signs and Greeks search for wisdom; 23 but we preach Christ crucified, to Jews a stumbling block and to Gentiles foolishness, 24 but to those who are the called, both Jews and Greeks, Christ the power of God and the wisdom of God.
Thus, knowing God starts with a step of faith in believing His Word, that He exists and is a rewarder those who believe.
For who has known the mind of the Lord, that he will instruct Him? But we have the mind of Christ.
Do you not know that you are a temple of God and that the Spirit of God dwells in you?
God's Spirit confirms with our spirits that we are members of His family. The Christian faith is a knowing faith for those who have believed the message! Even as it was back then when Paul penned these words, so it is today,
16 However, they did not all heed the good news; for Isaiah says, “Lord, who has believed our report?” 17 So faith comes from hearing, and hearing by the word of Christ. - Romans 10:16-17 (NASB)
I cannot help you believe. Do you hear the message? That is between you and God. All I can do is point you to the way.
John 14:5-7 (NASB)
5 Thomas *said to Him, “Lord, we do not know where You are going, how do we know the way?” 6 Jesus *said to him, “I am the way, and the truth, and the life; no one comes to the Father but through Me.
Oneness with the Father
7 If you had known Me, you would have known My Father also; from now on you know Him, and have seen Him.”
So, you hear these truths. What will you do with them? Will your heart be soft or hard towards God?
Hebrews 11:6 (NASB)
6 And without faith it is impossible to please Him, for he who comes to God must believe that He is and that He is a rewarder of those who seek Him.
God rewards our faith with our belief in Jesus Christ. He sends His Spirit to give us new life, eternal life. It starts with an understanding that God exists, we have wronged God, we are sorry, and that we are willing to repent and turn to Him through the means He has given.
Romans 10:8-13 (NASB)
8 But what does it say? “The word is near you, in your mouth and in your heart”—that is, the word of faith which we are preaching, 9 that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation. 11 For the Scripture says, “Whoever believes in Him will not be disappointed.” 12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, abounding in riches for all who call on Him; 13 for “Whoever will call on the name of the Lord will be saved.”
Do you hear God speaking to you? I will leave that between God and you to answer.
