What we are guaranteed is eternal life if we accept Jesus Christ as our Lord and Savior. John 3:16 teaches us that God gave His one and only Son, that whoever believes in him shall not perish but have eternal life. We also read in 1 Corinthians 6:19 that our bodies are temples of the Holy Spirit, who is in you, whom you have received from God. You are not your own.
What would happen if we took these scriptures and really applied them to our daily living? Our bodies are the temples of the Holy Spirit; that is all of it, your muscles, bones, and minds. But often we wait until is too late to attempt to take care of it, we live life eating unhealthy, not exercising and not feeding our minds with useful material to help us take care of it in order to enjoy those retirement years and actually have that time freedom we long for. The trips we aspire to take, the ministries dear to our heart we want to volunteer in and time with our families ends up taking a backseat as a result of how we took care of our bodies during our younger years. More often than none, we end up spending those years dealing with ailments or injuries that become a burden to ourselves and those around us. We see examples of this all around us and in our own families. Why is it so hard to take care of our bodies so that we can enjoy the life we long to as we age?
God designed our bodies to teach us about His care, be encouraged to see your bodies at the temple of the Holy Spirit. Be attentive to His leading and warnings over the years to take care of it and you will sure benefit from a healthier life here on Earth in the meantime.
