The Gospel is simply the good news. A summary of this good news is to biblically unpack the words God, Man, Christ, Response.
God
God is the creator of all things (Genesis 1:1). He is perfectly holy, worthy of all worship, and will punish sin (1 John 1:5, Revelation 4:11, Romans 2:5-8).
Man
All people, though created good, have become sinful by nature (Genesis 1:26-28, Psalm 51:5, Romans 3:23). From birth, all people are alienated from God, hostile to God, and subject to the wrath of God (Ephesians 2:1-3).
Christ
Jesus Christ, who is fully God and fully man, lived a sinless life, died on the cross to bear God’s wrath in the place of all who would believe in him, and rose from the grave in order to give his people eternal life (John 1:1, 1 Timothy 2:5, Hebrews 7:26, Romans 3:21-26, 2 Corinthians 5:21, 1 Corinthians 15:20-22).
Response
God calls everyone everywhere to repent of their sins and trust in Christ in order to be saved (Mark 1:15, Acts 20:21, Romans 10:9-10).
This is the core belief of UPCC and foundational to our walk with Christ.
