What are the basics of Christianity?

When rugby players start of their season, they always start off with the basics. These basics could include the following;
What does a rugby ball look like
How to pass a ball
How to kick a ball
How to tackle a player
How to cross the advantage line

This is a never ending cycle of events. Always some time or another, one always returns to the basics, always performs the basics, always executes the basics.

So one may ask; What are the basics of Christianity?

I have been given a view of this that I would like to share on a weekly basis, the first of which is the knowledge and ownership of eternal life.

1Jn 5:11-12 GW

(11) This is the testimony: God has given us eternal life, and this life is found in his Son.

(12) The person who has the Son has this life. The person who doesn't have the Son of God doesn't have this life.

With this knowledge, if we ever are confronted with questions concerning our faith or eternal life, lets be able to recite these verses!

2Ti 3:16 Every Scripture passage is inspired by God. All of them are useful for teaching, pointing out errors, correcting people, and training them for a life that has God's approval.
