There is no peace, no rest, apart from Jesus.
The peace Jesus gives is not a reward for anything - it is the free gift of Himself.
Only God can give peace. It is a gift from Him. It is the gift of His presence.
Thus the heavens and the earth were finished, and wall the host of them. And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done. So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation. Genesis 2:2
At that time Jesus declared, “I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and krevealed them to little children; yes, Father, for such was your gracious will. All things have been handed over to me by my Father, and no one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal him. Come to me, all who labor and are heavy laden, and I will give you rest. Take my yoke upon you, and learn from me, for I am gentle and lowly in heart, and you will find rest for your souls. For my yoke is easy, and my burden is light.” Matthew 11: 25-30
