"Not everyone who says to me 'Lord, Lord" will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven." -Matthew 7:21
Often times, people want to believe that all you have to do to be saved is say that you're a Christian. Maybe go to church a couple times a year, know the books of the Bible maybe, and just have a general "goodness", which is basically not being a terrible person by not murdering or stealing. Just do what you think is best and you'll go to heaven. However, we can see in Matthew 7:21-23 that we cannot do this. We have to do the will of the Father. But what is that will?
If you look at Matthew 28:19-20, as I'm sure you'll know, it says, "Go therefore and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold I am with you always, to the end of the age." This verse is often looked at as optional. Especially in the teen years, this can be looked at as, "Oh, I don't have to do this until I'm older." or "This is something I can't do until I'm on my own." However, this passage is directed to Christians, meaning, if you are old enough to be baptized, you are old enough to obey this command.
I have a question: Say you were in a car crash, a hit and run, and you were crushed under the weight of your car. You could get out from underneath it if you simply had the help of one person. Suddenly you see someone rushing over and without asking they pull you out of the rubble. A couple months later you see the same thing happen to another person. Now you walk by and see you have the full ability to help this person just like someone helped you. What kind of person would you be if you just ignored them? What kind of person would you be if you just left them in the rubble? As Christians, it's our job to go out and search for those people who are in the rubble, and save them.
As Christians we have a way to show others how to be saved not physically, but spiritually. Today I'd like to encourage you to find one person in the rubble, and help them out. Think of someone who you know needs help, and save them from eternal death. "The harvest is plentiful, but the laborers are few" (Matthew 9:37)
