As it's asked, this question doesn't make sense. It implies that it's what you do that makes you a Christian.
So if being a Christian isn't something you do, what is a Christian? Simply, a Christian is one in whom Christ dwells by his Spirit. It's a relationship between you and Christ. You put your faith and trust in Jesus, asking him to forgive and save you, and he does everything!
Can members of the Kiwanis Club be Christians? Sure. Are they all Christians? Surely not. Are Mormon's Christians? Surely some are, some are not.
Becoming a Christian is about putting your faith in Christ -- Paul writes in Romans Chapter 10:
"It's the word of faith that welcomes God to go to work and set things right for us. This is the core of our preaching. Say the welcoming word to God--"Jesus is my Master"-- embracing, body and soul, God's work of doing in us what he did in raising Jesus from the dead. That's it. You're not "doing" anything; you're simply calling out to God, trusting him to do it for you. That's salvation. With your whole being you embrace God setting things right, and then you say it, right out loud: "God has set everything right between him and me!
"Scripture reassures us, "No one who trusts God like this--heart and soul--will ever regret it." It's exactly the same no matter what a person's religious background may be: the same God for all of us, acting the same incredibly generous way to everyone who calls out for help. "Everyone who calls, "Help, God!' gets help." (The Message, Romans 10).
Have you made this call for help yourself?
