To rest in The Lord is to know the Love of the Father. So many christians suffer because of misinterpreted scriptures. Religious preachers with well meaning intentions actually portray God as a harsh God full of conditions and rules. In John 15 we are continually instructed to abide in Christ. He knows that this is how we produce fruit which glorifies God. As an apple tree doesn't strive to produce apples so a child of God doesn't strive to produce holiness, good works, and good character.
In my video you will find out how to abide in Christ.
