Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it. (Matthew 7:13-14)
Have you accepted Jesus as your Saviour, and think that's all you need to do? Is God happy with you sitting on your salvation, hoping to cruise right through the pearly gates to your eternal reward, even if it's just a cabin in the corner of glory? Then you are missing something very important in Scripture.
Jesus said that He is the Way. This tells of a journey, the road or means of getting somewhere. Jesus walked the Way perfectly, and we are to carefully observe what He did, then do it. First John 2:6 "He that saith he abideth in him ought himself also so to walk, even as he walked."
Jesus said that He is the Truth. Funny thing about the Truth is that it does not change. There's not "my way" and "your way", and we're all okay. Jesus IS the Truth, the living Word of God (John 1). Psalm 119:142 "Thy righteousness is an everlasting righteousness, and thy law is the truth." If you are not walking in this Truth, you are not walking with Jesus. At all. Period.
Jesus said that He is the Life. There is no life outside of Him. If He is not living in you and through you, then you are like a dead branch. Jesus is not your crutch to get into heaven, He is a way of Life.
You say that you are a Christian. Believers were first called Christians (little Christs) because their life, their speech, their way of living testified of Whose they were. Others in the world identified them as Christians. Would others identify you as a "little Christ"?
I'm glad that you have entered in through the Gate, which is Jesus. But realize that there is the Way (which is also Jesus). It starts just inside the Gate. Start walking in it!
