Toddlers focus completely on what they are reaching for. It doesn't matter if it is out of their reach, a toddler will continue to stretch and reach for the desired object. In the same way, followers of Jesus need to focus completely on Jesus. He is the prize. Our conversations should reflect this focus. Cursing, gossiping, and bad mouthing have no place in the lives of Christians. Are we perfect? No. However, we should be striving to be more like Jesus. Keep your focus on Christ, not on the earthly temptations that surround us. Have the focus of a toddler.
"He who runs a race, must never stop short of the end, but press forward as fast as he can; so those who have heaven in their view, must still press forward to it, in holy desires and hopes, and constant endeavours. Eternal life is the gift of God, but it is in Christ Jesus; through his hand it must come to us, as it is procured for us by him. There is no getting to heaven as our home, but by Christ as our Way". Matthew Henry's Concise Bible Commentary
