Q. Why I came here?
A1. I came here because Christianity - Stack Exchange is a question and answer site for committed Christians, experts in Christianity and those interested in learning more. [...] I was hoping to help build a library of detailed answers to every question about Christianity.
A2. In addition to the reason above, I was hoping to help, if I could, prepare myself and all Christians make a defense to any one who calls us to account for the hope that is in us [cf. 1 Pet 3:15].
In the Prayer of Saint Ignatius
Teach us, good LORD, to serve you as you deserve; to give and not count the cost; to fight and not heed the wounds; to toil and not seek for rest; to labour and not to ask for any reward, save that of knowing that we do your will. Amen. - Source: A Simple Prayer Book | CTS.
and in you the good and generous paymaster, we hope,
3 And those who are wise shall shine like the brightness of the firmament; and those who turn many to righteousness, like the stars for ever and ever. - Dan 12:3 (RSVCE).
