Matthew 5:12 Rejoice and be exceedingly glad, for great is your reward in heaven, for so they persecuted the prophets who were before you.
One of the things you may struggle with is working out whether you have to do anything in order to gain this great reward from God in heaven… until you trust Him and He shows you the answer!
God does not require us to work hard in order to gain this reward; it is a gift from Him and is not a reward for working hard but for believing in Him.
Many people before us have had to endure many hardships because of their belief in God; we should expect some hardships to come our way when we say that we do believe.
