Now your iPhone / iPod Touch is a missionary, preacher and the evangelist!!! The iPhone / iPod Touch application "iChristian" ("Become a Christian") contains the minimum of required information to become a Christian. Alter the prayer of salvation. you may register as a Christian. If you would like, you may request a certificate of a Christian.
If Jesus warned those wanting to become His disciples that they must count the cost of following Him, then for us to offer salvation to unbelievers through such a come-on line as "contains the minimum of required information to become a Christian" is to mislead them. It's spiritual bait-and-switch...
We have no spiritual or religious product that can be bought at the Dollar Store. Following Jesus has, and will, always cost a man his very life. Believing in the Death and Resurrection of our Lord is to take up our cross and follow Him.
Now large crowds were going along with Him; and He turned and said to them, “If anyone comes to Me, and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be My disciple. Whoever does not carry his own cross and come after Me cannot be My disciple. For which one of you, when he wants to build a tower, does not first sit down and calculate the cost to see if he has enough to complete it? Otherwise, when he has laid a foundation and is not able to finish, all who observe it begin to ridicule him, saying, ‘This man began to build and was not able to finish.’ Or what king, when he sets out to meet another king in battle, will not first sit down and consider whether he is strong enough with ten thousand men to encounter the one coming against him with twenty thousand? Or else, while the other is still far away, he sends a delegation and asks for terms of peace. So then, none of you can be My disciple who does not give up all his own possessions. Therefore, salt is good; but if even salt has become tasteless, with what will it be seasoned? It is useless either for the soil or for the manure pile; it is thrown out. He who has ears to hear, let him hear.” (Luke 14:25-35)
