To better understand how the new covenant that God has made with man applies to you:
Read God's word, pray and seek counsel from a pastor or lay person of a bible-believing church.

Remember, the only condition for salvation from your sins is that you have faith, and believe in Jesus Christ as the one and only sacrifice who died on the cross for the sins of the world, rose again on the third day, and sent His Holy Spirit to live in the hearts of all who believe.

Jesus' promise to us to keep his covenant of salvation for anyone who believs in Him comes with the gift of eternal life.  Because He lives, I too shall live!

"Only believe??" you ask.
Abraham was a man whose faith was considered by God to be righteousness, (Genesis15:5-6).
God made an everlasting covenant
with Abraham, promising him
land, a seed, and a nation, (Genesis 15),
and said that through Abraham all nations would be blessed, (Genesis 12:3).
The seed that Abraham was promised was His descendant, Jesus.

Through Jesus all men, Gentiles as well as Jews can enter into the New Covenant
with God. Romans 1:16 says..."[The Gospel of Christ] is the power of God to salvation
for everyone who believes, for the Jew first and also for the Gentile." Romans 1:16

I pray, if you do not know Jesus as your Savior, that you would go to Him in prayer now and ask Him to cleanse you from your sins by believing and trusting in His work done on the cross to bring you back to God.
When you decide to do this and totally trust in Him, surrendering all of your plans to receive what God has for you, He will give you so much...
...eternal life, a new life here on earth through
the gift of the Holy Spirit and a knowledge that
God's plans for you will always work for your good.
Only trust Him, now...
He will save you, now!
