Not intended to be exhaustive. From my blog Interpreting the Cosmos:
The Christian worldview is that there is one true God, eternal, uncreated, existing in three Persons, co-eternal, each one being God in all His attributes.
He is the Creator of all things, and He has created humankind for His own glory and purpose – chiefly so that we might know Him, honor Him for who He is, and enjoy His good gifts forever.
There is evil in the world because humankind chose to reach for autonomy from Him, to be “as gods.” We tried to become our own judge, our own standard of good and evil. This has resulted in the evil and chaos in the world – all sin and brokenness a result of this disconnection from our true relationship with God.
Although God is within His right as the Sovereign Judge to allow humanity to fully perish in sin, He yet intervened to save a vast multitude. He has done this through choosing a people, the descendants of Abraham, with whom He made an unconditional covenant of grace. Through the history of Abraham’s descendants, God has been slowly revealing His greatest moment of glory – the birth, life, death, burial, resurrection, ascension, and intercession of His Son Jesus Christ, who though eternally God chose to empty Himself to become a man, born of a virgin, and at the end of His life, the penal substitution before God for all who would ever trust Him and thus receive His forgiveness and salvation.
We need a Christian worldview because most people do not believe this is the real history of God’s interaction with the cosmos (world). When people believe other things, and do not repent of their own religions and sins, they cannot be reconciled to God in Jesus Christ. They must hear His gospel and be baptized into Him – and He receives all who come to Him, never casting even one person out.
The Apostle Paul tells us that “though we walk in the flesh, we are not waging war according to the flesh. 4 For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. 5 We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ…” (2 Cor. 10:3-5 ESV).
That is the battle cry for us to wage a war of truth against Satan’s world of lies. We are to use God’s Word to cut down arguments that are exalted against the knowledge of God so that the people in bondage to lies can be set free in the love of Jesus Christ.
Jesus will return to judge the living and the dead – there will be a resurrection of all people, some to hell, some to the presence of God in a renewed heaven and earth. Those who have turned to Christ Jesus will be received into the presence of God as if they were Jesus Himself, having received His own righteous standing before God as He Himself received our sin and condemnation on the cross.
In the end of all things, Jesus will reconcile all things to Himself in that nothing in the universe will be independent of His rule and reign, and all things will acknowledge that perfectly.
And, I should add this as well – that in Jesus Christ are hidden all the treasures of wisdom and knowledge (Col. 2:3). No human being knows anything apart from Christ having given them life, logic, reasoning, and the spirit of inquiry. This is the common basis for all human beings: we are created by the Son of God, and for the Son of God. Any structures of philosophy and religion which do not place Him at the blazing center of thought are faulty structures.
The fear of Yahweh is the beginning of knowledge (Prov. 1:7). We can know nothing apart from Him. We cannot justify one iota of our knowledge without beginning with Him. This is the Christian worldview.
