We might not be able to improve or change a whole lot of things about us, but we can indeed have that happen with our feet as we obey the Lord reaching out to others. Yup, according to the apostle Paul, we can have beautiful feet as by faith they hit the street: "How beautiful are the feet of those who preach the gospel of peace, who bring glad tidings of good things!" 10:15rom.
Spreading the far-beyond-great Tidings of Jesus' Gospel isn't really just the responsibility of trained Bible teachers and professional church pastors in some contained kinda religious or non-religious nook. All who know Jesus personally are also privileged and called to share Him in or outside a nook.. on a personal level with people even beyond Facebook.
Lord, we are willing to be used of You in witnessing daily, so please give us boldness and wisdom so that we each can present the truth in a way that would be just right for each person that we meet. We want feet just like Yours in relation to the Great Commission. Thanks Jesus.
