One meaning of Gospel is, 'the teachings of Jesus and the apostles.'
It also means that 'God loves you.'
It originated from god + spell, god (good) + spell (to tell).
God has a purpose for your life, and He wants you to have a meaningful life. He wants you to experience His love by living our life 'His way' rather than 'our way.' God sent His only son, Jesus Christ into this world to show and teach us 'His way' of living, and 'His love; towards us.
Through Jesus, we can certainly see the right path to lead and the epitome of love. That is the Gospel.
