The message of the Gospel is true, no matter who preaches it. God does not change. If we believe the gospel is true, we will be changed, if we don't believe the gospel is true we will regret it. There is nothing on Earth that can compare to the joys of Heaven. The reason why God's children are here is for the spread of the gospel. There is hope and Jesus Christ came to save sinners. Jesus will give us brand new lives. Suffering for Jesus is a privilege and gift. God is not the author of sin and God is in total control. In the midst of persecution, we don't need to enjoy it, but we should rejoice in the Lord.
The Book of Hebrews is written to Jewish believers in Christ who were tempted to not follow Jesus wholeheartedly. Instead, they and we today, are called to follow Jesus through obedience and faith. We are supposed to be aiming for Jesus. Following Him will involve a cross and daily death. Everything we want to do should be pleasing to the Lord. We must persevere or we were never Christ's. We must encourage each other daily because sin deceives and cannot deliver. If we want to do the will of God, He will ensure that we do.
