Christians who use tumblr:
"….Social networking can also be abused. When it consists of nothing more than random babblings and personal monologues, it can become self-centered, unrestrained and narcissistic. When it consumes our lives, it can be addictive and controlling. Used unwisely, it is filled with potential pitfalls and temptations. For those who follow Christ, we are called to submit every area of our lives to His lordship—including how we use social media.
As believers, we are called to love, encourage, instruct, admonish, and serve one another. That requires far more than social media can provide. The life-on-life discipleship that characterizes Christian friendship goes much deeper than any Facebook update or Tumblr post..
As believers, the command of Ephesians 5:15–16 is just as binding upon our modern lives as it was in the non-technological world of the first century. “Therefore be careful how you walk, not as unwise men but as wise,making the most of your time, because the days are evil.” Paul’s exhortation has massive implications for how we interact with social media. One day we will stand before Christ to give an account for how we used His resources (including our time and energy). With that in mind, how much of this life can be justifiably devoted to Twitter, Facebook, YouTube and the like? Just a few hours each day, over the course of a lifetime, adds up to years of wasted opportunity.
When so much about social media panders to pride and shameless self-exaltation, believers need to think about their motives before they jump on the bandwagon. If the goal is simply popularity or personal promotion, it’s time to do a heart check. Our celebrity-driven culture craves for notoriety. But Christians are called to be different. We have died to ourselves. Thus, our concern should not be, “How many people can I get to follow me?” but rather, “How can I bear witness to the wonder of following Christ?”
Social networking can be a useful tool when it is used in moderation and for the right things. At the same time, however, pitfalls and temptations do exist; and believers need to arm themselves accordingly. Social media are obviously not going away any time soon. But that doesn’t mean we can be undiscerning in how we approach them.
Moreover, believers need to be careful what they communicate to the world about their lives. Once something is posted online it can be seen by anyone else. Once it’s cached, there is a permanent record of it. That means every status update and every tweet is part of the believer’s public testimony as a Christian.
As Paul told the Galatians, “I have been crucified with Christ; and it is no longer I who live, but Christ lives in me; and the life which I now live in the flesh I live by faith in the Son of God, who loved me and gave Himself up for me” (2:20). Like Paul and every other believer, my life is no longer my own. The focus must not be on me, but on Christ. When someone hears from me publicly, I want it all to point to Him.”
