The NLT is a wonderful translation, because its in plain modern English.
When we first give ourselves to Christ, a lot of old dead emotional and spiritual weight comes off, so following Christ becomes so joyful. the rest he gives come from no longer spiritually striving, and just living in freedom from being in relationship with god because of his forgiveness. I want to thank you and encourage you to keep posting @jstajok, your reminding people they can come to God for comfort rest with this post. :)
