The verse: Hello, God has given me something in 1 Kings 8:56 which says,
“Praise be to the Lord, who has given rest to his people Israel just as he promised. Not one word has failed of all the good promises he gave his servant Moses.”
God’s rest: So, what God has given me, is, that at the cross Jesus gave us rest, so now we have rest, and Jesus died on the cross for us, and we can go to heaven! So we get eternal life (Mathew 25:46), and peace (Isaiah 9:6). Mathew 25:46 says,
“And these will go away into eternal punishment, but the righteous into eternal life.”
Eternal life: So Jesus is saying that the wicked will go to eternal punishment, while the righteous into eternal life, and Jesus makes us righteous. Isaiah 9:6 says,
“For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.”
Jesus: So Jesus is our prince of peace, and everlasting father, mighty God, and wonderful counselor. Jesus died on the cross, so that we could (and can) have those things, the peace, the love of the father, and a wonderful counselor.
