Are you a believing Christian by word of mouth or by your fruits? Or are you a Christian just because you go to church? Christ stated clearly that you will know them by their fruits. Therefore, if you are a believing Christian, you are to behave like one.
You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? Even so, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Therefore, by their fruits you will know them - Matthew 7:16-20 (NKJV).
A good man out of the good treasure of his heart brings forth good; and an evil man out of the evil treasure of his heart brings forth evil. For out of the abundance of the heart his mouth speaks - Luke 6:45 (NKJV).
A person is not known as a 'Christian' just by his or her religion. Rather a true Christian is known by his or her fruits. Therefore, bring forth fruit that depicts you as a Christian if you're one. The disciples were first called Christians because they were behaving like Christ. So also, people will acknowledge you as a true Christian when you behave like Christ.
A true Christian is a person who has accepted Christ as his or her Lord and personal saviour and behaves like Him. That is, the person is a bornagain child of God and does what pleases the Father as Jesus did.
A Christian is known by his or her words and actions. This is because from the abundance of the heart the mouth speaks (Luke 6:45). And as a man thinks so is he (Proverbs 23:7). Therefore, you are known as a believer and disciple of Christ by your lifestyle.
According to Romans 12:9-21, there are certain things you need to do as a lifestyle if you are a Christian. These include loving without hypocrisy and abhorring evil; clinging to what is good; brotherly love; diligence and fervent in spirit; serving the Lord with everything in you; rejoicing in hope and with others; patience in tribulation; steadfast prayer; hospitality; bless and do not curse those who prosecute you; being humble and living peaceably; do not be overcome by evil but overcome evil with good.
It is not enough to declare that you are a Christian. Rather, set an example and show it by behaving like one. Truly, by your fruits, everyone will know that you are a follower of Christ. Therefore, learn how to behave like a Christian o child of God and do likewise today.
