I chose to be strengthened and the reason is very simple. It's in the Bible and we are told about this two thousand years ago that some will give up their faith in the last days and turn away from God (1 Timothy 4:1) 'These' people God spoke about are believers. As you examine this letter by Apostle Paul to Timothy, the people that going to turn away are not just ordinary believers, they are people who are religious leaders.
We believe in the Bible. We don't go and keep records of the names of pastors, evangelists, etc who have given up their faith and to also keep names of ex-Buddhists, ex-Muslims, ex-Hindus who have become Christians and then make our decision whether we should continue with our faith or to give up our faith. This is totally irrelevant.
