How do we behave like Christians?
1) We have to love without hypocrisy. What does this mean? One definition of love is "the fulfillment of the law", meaning that "loving your neighbor as yourself, not coveting, not committing adultery and such is what love is. Second, Jesus Christ, who loved the Church to the point of death (Ephesians 5) is the ultimate example of what love is. He displays his love to his apostles, gentiles, his enemies, Israelites, up until his death and then his resurrection. (All the gospels). Actually, love and hypocrisy are like watter and oil, they just don't mix.
2) We have to "abhor" evil, aka SIN, and cling to what is good. I do not know about you, but this is constant battle that I go through daily, at work, home, basically everywhere. As Romans has shown us in the previous chapters, we are sinners by nature. As believers, we have a few weapons to help us accomplish "abhor sin". (It requires us to work daily on this) God's word. It's the only book who we can trust to guide us through daily life. The book of Timothy is a great book for younger Christians. The book of Peter is also great for direction regarding obedience, caution regarding false doctrines, his second coming, etc. A second weapon is PRAYER, a privilege that God has given to us to speak to him directly, to Adore, Confess, Thank and supplicate (or ask). ISN'T THIS AWESOME!!
3) Cling to what is good. If we abhor sin, we are free to cling to what is good. Of course we have to strive to do it. If you think about it, clinging to what is good comes naturally when we're able to work through the previous two qualifications. I realize I made it sound simple, but on the contrary, it is a life-long process and as such, we should make it part of our daily lives.
4) Be kindly and affectionate to one another, with brotherly love. Jesus displays brotherly love to EVERYONE throughout all the gospels, so does Paul. (Note that brotherly love also includes exhorting and correcting one another)
5) in honor giving preference to one another. Loving our neighbor as ourselves includes putting someone else before us. It is very easy to display this with family members, your best friend. But what about with the "unpopular kid at school", or someone who did not pick you to be on their team. Our behavior toward these individuals really shows us and everyone else, if we're truly behaving like Christians.
See ya.
