You need to be aware of the fact they are watching especially if you are a Christian. If they are watching what you do and say, it will have an effect on their life. The bible says in Matthew 5:13 that you are the salt of the earth, meaning that according to what you do and say your actions or words have an effect on people’s lives whether you are aware of it or not. I had no idea that my neighbor was watching what I did but as soon as there was a change to our routine he noticed. That is the very reason we are to be exactly the way Jesus is.
The way Jesus is in heaven, so are we here on earth. The things you say and do can carry life or death. You might say that is really radical and how can my life be the difference of life or death? Easy to answer, if you profess to be a Christian and you act the same as the world, why would anyone want to follow Jesus? That person that may be watching you may be on the verge of surrendering their life to Christ and they see you and watch your actions and begin to think why should I follow Christ because what they have is no different from what I already have and they reject Him only to die the next day having never received Jesus in their life, the difference between life and death.
We have power in our words and in our actions, and the sooner we recognize that, the more effective we are going to be in our witness to others. We need to determine in our hearts that regardless of what is going on around or in us we need to be the witness for Jesus that He wants us to be. You witness with your actions and with your words. You must be the same way Monday through Saturday as you are on Sunday. God has called us to be righteous and to be a witness to those who do not know Him. When we bless others, in turn we are blessed, the theory of sowing and reaping, or to put it another way, what goes around comes around.
Be always vigil to be the person God has called you to be and always be aware of the fact that what we say and what we do is noticed by others around us. We need to be like Christ 24/7 and there is no other way to be. Be the love of Jesus to everyone and you will be effective in your quest to see lost souls surrender to Him. 1John 4:17 this is how love is made complete among us so that we will have confidence on the Day of Judgment: In this world we are like Jesus.
Christ is our rock and if we will stand upon Him we cannot fail.
Jesus loves you!
