I believe that one of the greatest opportunities we have as Christians is to make a profound difference in the lives of others. Throughout my life of ministry, God has given me the opportunity to help many people who need guidance. 

But I don't believe this is a special opportunity that God made just for me. Everyone, you included, has the ability to influence someone. When we take the time to reach out to others and invest in someone's life, we are impacting the world...yours and theirs. 

Galatians 6:10 tells us to "be mindful to be a blessing" to everyone God brings across our path. We are called to be a blessing and build up others in their faith, to not be afraid to reach out and to speak the truth in love. 

I don't believe God wants us to be mere spectators in life. He wants us to be people who really love others and care enough to be willing to pour into their lives. We need to build up others in Jesus' name so they can grow and reach even more people. 
Whether you know it or not, someone's watching and looking up to us. People are influenced by the way we live and they need to see God's love in our everyday actions. 

At times we'll make mistakes, and when we do we can thank God for His forgiveness, but we also have to realize that many times we may be the only evidence of God some people see. 
So then, as occasion and opportunity open up to us, let us do good [morally] to all people [not only being useful or profitable to them, but also doing what is for their spiritual good and advantage].

Be mindful to be a blessing, especially to those of the household of faith [those who belong to God’s family with you, the believers]. (Galatians 6:10 AMP)
