If everyone in the world followed the New Testament literally following Jesus there would still be strife. Jesus' disciples competed for the Top Disciple title, which to be selected as "greatest". They asked in Matthew 18:1 "At the same time came the disciples unto Jesus, saying, Who is the greatest in the kingdom of heaven?" Again, in Matthew 20:[20] "Then came to him the MOTHER of Zebedee's children with her sons (APOSTLES), worshipping him, and desiring a certain thing of him. [21] And he said unto her, What wilt thou? She saith unto him, Grant that these my two sons may sit, the one on thy right hand, and the other on the left, in thy kingdom." Later in verse [24] "And when the ten heard it, they were moved with INDIGNATION against the two brethren. [25] But Jesus called them unto him, and said, Ye know that the princes of the Gentiles exercise dominion over them, and they that are great exercise authority upon them. [26] But it shall not be so among you: but whosoever will be great among you, let him be your minister;"
Folks still haven't figured it out...but there is a way, the only way in Christ.
Jesus warned He didn't come to bring world peace but a "sword" among family members. Search it out in the Bible, as it is a very interesting study.
You do what God wants you to do and you will do well. Start with Jesus as your savior and lord.
