Let's begin with the backstory. God is infinitely good (Ps 136:1), holy (Isa 6:3), and perfect (Ps 18:30). On the other hand, Man draws a stark contrast to God’s purity. We are born in iniquity (Ps 51:5), and continue in unrighteous (Rom 3:10), completely dead in our sins (Eph 2:1).
Now, for the “bad news”: We are judged as guilty (Rom 6:23) according to God's righteous judgement (Ps 7:11). Since, God is a perfect judge- the very definition of righteousness- He cannot merely look over our sins and infractions of His law. Nor, can we hope for a clerical error for He sees and knows everything (Heb 4:13)! He must judge sin as sin and punish sin with death to uphold His righteousness. Moreover, we cannot plead ignorance for He revealed His law through our conscience (Rom 2:14-16).
“The wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” (Rom 6:23)
Jesus Christ saves from the "bad news".
All the good of the Gospel is found in Jesus Christ. Only He can restore man’s relationship with God (2 Cor 5:18), a restoration dependent on His humanity and divinity: His sinless life (2 Cor 5:21), His death on the cross (Heb 9:22), and His resurrection from the dead (2 Tim 1:10). All drawn to Christ by God will be saved (John 6:37). Furthermore, once received into God’s kingdom; none can lose, nor build upon the saving grace of Jesus (John 10:28).
In order for us to participate in the saving work of Christ, we must receive the call of God’s irresistible grace. Life in God begins, not in our birth, works, or religion, but in God’s will (John 1:13). He selects us and bears us into His kingdom by the power of His Holy Spirit. The Holy Spirit convicts us of our sins (John 16:8) and leads us to repentance. We repent of our sins (Acts 2:38) and turn to Christ, declaring His Lordship with our lips and believing in His divine power with our hearts (Rom 10:9). So, God plants faith in the heart of man by His spirit and word (Rom 10:17), and man responds in faith considering God’s righteousness (Rom 3:22).
But, this is not a mere lip service (Isa 29:13; Matt 15:7-9). God’s spirit empowers the believer in continual devotion to Him (Acts 2:42) and enables a tireless meditation upon the words of Christ (John 8:31). God transforms the heart of dead men with a living spirit (Ps 51:10; Rom 12:2) and allows us to enjoy the fruits of His spirit: patience, love, mercy, and grace (Gal 5:22). This is the new birth into the kingdom of God through Jesus Christ (John 3:5-8). While we continue to fight our lusts (1 John 8), God credits Jesus’s perfection to us (Rom 4:24-25) and by the power of His Holy Spirit continues to purify us on earth until He perfects us in heaven (Heb 6:1; 1 Peter 5:10).
