Trying to be good or healthy doesn't always work. But when we find the truth that we are inherently spiritual as God's expression, then being good and healthy becomes natural.
A little girl once said to her brother:
"I tried with all my might to be good, and I prayed and read my Bible, but I was no better. At last I found Christ, and when I found Christ it was all easy; and from that time I have been so happy."
The Bible says,
"Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new." -2 Cor. 5:17
I've seen many people washed clean of negative feelings and dis-eases of the past by finding Christ and living in Christ. What is Christ? Christ is Jesus' divine nature -- and our real nature too. Christ is the heartbeat of Jesus' teachings. Christ is the truth that life, including you and me, is spiritual, sinless and Soul-sustained.
Living in Christ, being good and healthy and happy is more than natural. It's inevitable.
