Jesus paid the price of suffering and death for our sins to make a way for us to be reconciled to Him. We have peace with Him by His blood if we obey the gospel.

"And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven. And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight: if ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel, which ye have heard, and which was preached to every creature which is under heaven; whereof I Paul am made a minister;" - Colossians 1:20-23

What is the gospel?

"For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; and that he was buried, and that he rose again the third day according to the scriptures:" - 1 Corinthians 15:3-4

"Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost." - Acts 2:38

We can walk with God once again, with His Spirit within us.

"For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call." - Acts 2:39

The preacher pleads –

"And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation." - Acts 2:40

How can we respond?

"Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls. And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers." - Acts 2:41-42

Repentance (turning from sin and turning to Jesus), water baptism by immersion in the name of Jesus for the washing away of sins, receiving the gift of the Holy Ghost with the sign of speaking in other tongues as the Spirit of God gives the utterance, continuing steadfastly in the apostles’ doctrine, not forsaking the assembling together… and so much the more, as you see the day approaching. (Acts 2:4, Hebrews 10:25)
