There is nothing like personal contact. The internet cannot substitute this. I have been involved in internet connecting with other ministries since 1999. It has been very rewarding but I have yet to see it have the effectiveness of personal contact.
I have had my share of false people. I have also made some lasting friendships.
Let us pray that God helps us to discern the boundaries of proper internet use. Things so powerful like Facebook and Twitter can take over your day. We must minister unto the Lord. Fellowship with the Lord cannot be interfered with by technology.
Personal contact gives us warmth, sincerity and less chance for misunderstandings to arise.
Let us also use internet wisely.
