Look, don’t judge Christianity by the imperfect examples that we have seen in history. Judge it by Jesus Christ.
God often goes to the gutter to find the recipient for His grace. He lifts him out, washes him and transforms him – making him into a child of God fit for His kingdom. That is God’s grace.
The most important thing a born again Christian can do is to pray.
You have only one life and it will soon be past, and only what’s done for Christ will last.
