The only "getting ready" I know about--whether alive or dying--is to know Jesus Christ our Savior and accept His life, death, and resurrection and His righteousness to cover our sinful natures. That is the white garment, and it is easy to ask for. Good works don't do it, but they will follow those who ask for His Spirit. Not all have the same gifts, and we are not to feel guilty if we don't excel at the same type of soulwinning or evangelism as someone else might.
