As believers, we are called to let our light shine in this world, but we must always remember that the glory belongs to God and not to ourselves. Scripture teaches both humility and faithful service, and these truths do not contradict one another. God has given every believer abilities and opportunities to serve Him, and those gifts are to be used so that others may see Christ and be pointed to the truth of the Gospel. Whether through preaching, teaching, helping, or simply serving others faithfully, believers are to use what God has given them for His glory.
Jesus Christ is the perfect example of this balance between power and humility. Though He is the Son of God, He humbled Himself and became a servant, obedient even unto death on the cross. As Christians, we are not to seek attention or praise for ourselves, but we are to faithfully do the work God has called us to do. When believers walk humbly before God and serve Him faithfully, their light will shine in a way that points others to Him.
