Jesus saves.
For the grace of God has appeared, bringing salvation for all people, (Titus 2:11)
What are we saved from?
His wrath.
among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. (Ephesians 2:3)
when the Lord Jesus is revealed from heaven with his mighty angels 8 in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus. 9 They will suffer the punishment of eternal destruction, away from the presence of the Lord and from the glory of his might, (2 Thessalonians 1:7-9).
Why do I need saving from His punishing wrath? I'm a good person.
No, you're not. Neither am I.
for all have sinned and fall short of the glory of God. (Romans 3:23).
If I'm a sinner as you say, and headed for His wrath, how can I be saved?
because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. 10 For with the heart one believes and is justified, and with the mouth one confesses and is saved. (Romans 10:9-10).
How did this come about?
For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, 4 that he was buried, that he was raised on the third day in accordance with the Scriptures, 5 and that he appeared to Cephas, then to the twelve...(1 Corinthians 15:3-5).
Did Jesus really rise up from the dead? Come on...
For if the dead are not raised, not even Christ has been raised. And if Christ has not been raised, your faith is futile and you are still in your sins. (1 Corinthians 15:16-17)
Well when you put it like that.
I don't put it like that. The Bible puts it like that. Furthermore,
Jesus came into Galilee, proclaiming the gospel of God, and saying, "The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel." (Mark 1:14b-15)
Now. Now is the time.
