As humans, we are not designed to carry the weight of the cares and burdens that we carry today. We were created to enjoy or work and take care of the earth and make it a paradise. But, because of sin toil and hard labor came into the picture. But when Jesus Christ came and reopened the door to more heaven like a lifestyle now called Christianity we are and should take every advantage of the potential carefree living it gives us glimpses of.
You see Jesus Christ knew that it would not be all peaches and creme for us once He returned to His Father because there were still many adversaries in the land. Extreme haters if you will call devils and demons. But, by the indwelling of God's own Holy Spirit we could have the ability to be in this world but no longer of it. It's called Being Born Again.
That through the Holy Spirit we could have a witness on the inside that would testify as to how things operated in Heaven. The Bible calls Him Heavenly treasure placed in earthen vessels. So, all thought Jesus's time on the earth He continued to encourage the disciples to take no thought for their lives (Matthew 6:25) and called worrying about even simple things like what to eat or drink or wear a sin.
A carefree lifestyle afforded to those that would dare to put their complete and total trust in Him. Wow, isn't it amazing? The teaches of Jesus Christ spells it all out in great detail that if we are to labor we must labor to enter into his rest. His rest says that we are to take on His yoke for His yoke is easy and His burden is light (Matthew 11:28-30).
"And the cares of this world, and the deceitfulness of riches, and the lusts of other things entering in, choke the word, and it becometh unfruitful." Mark 4:19 kjv
So living a carefree life is only possible while abiding is Jesus Christ The Son of the Living God (JEHOVAH). The alternative is to live a life of struggle, heartache, and pain with the only solutions being that which the world has to offer. Drugs, violence, sex, and entertainment.
To know Christ is to know peace. To know peace to live truly carefree.
