If the Lord comes, then I'll get saved

This is a totally precarious stance to take on 2 counts.

1. None of us know how long we will be here. The cemetaries are full of bodies of all ages. You could die in your sins and then all hope will be lost forever.
2. The Lord could return at anytime. His coming will be unannounced and will occur in the twinkling of an eye. In a moment those who are saved will be gone, to forever be with the Lord and you, if unsaved, will be left behind for judgement.

For those who think that if the Lord comes before they die, then they'll believe...

I will get saved but not right now

Sometimes, you come across individuals who know that they need to be saved but they plan to get saved later. There's no hurry and they are enjoying themselves so much at the moment.

Perhaps such have been born into Christian homes, that is, their mother and father are both saved. In any case, they have heard the gospel message and that is a blessing but with it comes tremendous responsibility. To have heard the message of the gospel; to know that you're a sinner, to have heard that there's a God who loves you and that there's a Saviour who died for you; but to have reckoned this knowledge of little importance, to be thinking there's no urgency.

Christianity has been dreamt up to give comfort

It has been said to me that Christianity was just a concept dreamt up years ago to give those who believed in it a certain amount of comfort with regard to what happens after you die.

What think ye of Christ?

It's a question we all must answer "What think ye of Christ?" (Matthew 22:42)

As the hymn-writer puts it,

What think ye of Christ? is the test
To try both your state and your scheme
You cannot be right in the rest
Unless you think rightly of Him

I'm a good person!

To do good unto others is commendable but we are all measured according to God's standard and the bible teaches us "...all have sinned, and come short of the glory of God;" (Romans 3:23)
"Behold, I was shapen in iniquity; and in sin did my mother conceive me." (Psalm 51:5)

God's standard is infinitly higher than ours. We, so easily, argue away our sin. We minimise it, we deny it, we categorise our sins so that some become so small in our eyes, that they don't really seem to count.
But in God's judgement we "...are all gone out of the way...there is none that doeth good, no, not one." (Romans 3:12)

God is a God of love and so He won't punish me!

Often I come across sincere people who believe that God won't punish them for their sins; that somehow He will forgive them because, after all, He is a God of love.

My first response to this is that God is indeed a God of love!
"For God so loved the world, that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life" (John 3:16)

Caught up in the Rapture debate

Firstly, to clarify, rapture is not a word that is found in Holy Scripture. There are numerous words not found in scripture, however, that are perfectly acceptable to explain scriptural truths, millennium, trinity, divinity, incarnation.

The word rapture is derived from the Latin bible, Vulgate, and is a rendering of the word 'raptus'. It is a Latin rendering of the Greek work 'harpazo' which means to 'snatch out' or 'to seize'.
 There are those who deny that any such 'rapture' of the saints will take place at all. They refer to such an event under the erroneous umbrella of 'rapture trap' or 'left behind' theory.
