Charles Spurgeon said the following:
“The raw material for a devil is an angel. The raw material for the son of perdition was an apostle; and the raw material for the most horrible of apostates is one who is almost a saint.”
Playing around with Christianity, pretending to be familiar with Christ because you know a couple verses, said a few prayers and went to a few churches, is not necessarily getting you ready for heaven.
It could be you are laying the groundwork for the great falling away, the huge apostasy predicted for the end of this age. Make your calling and election sure. Test yourself whether you are in the faith.
