Deuteronomy 31:6
Be strong and of a good courage, fear not, nor be afraid of them: for the LORD thy God, he [it is] that doth go with thee; he will not fail thee, nor forsake thee.
In Deuteronomy we learn that we should be strong, and of good courage, and not to be afraid, because the Lord is with us always, and will not leave us alone.
1 Peter 5:7
Casting all your care upon him; for he careth for you.
Cast all your cares and worries on Him, because he can handle, what we cannot.
1 Peter 2:24
Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.
Christ died on the cross for our sins, so that we could live. We are healed, all we have to do is to accept Christ into our lives.
2 Corinthians 5:17
Therefore if any man [be] in Christ, [he is] a new creature: old things are passed away; behold, all things are become new.
If we are in Christ, it does not matter what type of life we have lived before. He has cleaned our slate, and made it new again.
Isaiah 53:6
All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all.
We have all sinned and come short of the glory of God, however, Jesus died on the cross for our sins, that we may be renewed and live. Jesus rose after three days, and ascended into heaven. Now, He is preparing to come again.
