Blessed are they that mourn: for they shall be comforted. Matthew 5:4"
As a child of God, sometimes take time to ask yourself the following questions: how did I become a born again Christian? Where would I have been if I were not born again? What is my Christian life like without winning a soul? If these questions are honestly answered, you will have compassion for any lost soul you come across in your day-to-day endeavor.
The Christians who mourn/prayerfully fight for lost souls will be blessed and comforted with good tidings and benefits. Everybody became born again because someone preached to him or her; even if you were reading the gospel/Bible and you became born again, you were convinced by the Holy Spirit.
Everybody needs somebody; therefore, if you see a drunkard, prostitute, thief, gay person, etc, mourn for them in prayer and extend the good news to them so that the LORD can reward your effort. Remember to show them the love of Christ.
Hallelujah!
