In the society we live we are more safe in our environment if we are followers of good. I am not sure about the statement about happiness when we suffer for doing good, but it is the word of God and I must accept it that way. So far I have not experienced that so I can't say. The term sanctify the Lord God in your hearts means that Christ should be everything to me and when the time comes that someone would ask me why I live like I live, I can tell them that they need the Lord Jesus Christ, and they can have the same kind of heart happiness I have. Then I can lead them to trust Christ for eternal happiness. A conscience is what Adam and Eve got when they ate of the tree of the knowledge of good and evil. However, there are people with a good conscience and evil consciences. When we trust Christ and live for Him we have a sanctified conscience and believe me it does make a difference. Christ the totally "Just One" suffered for me the not just one. He brought me to God through the blood of His cross. Now I am free. Baptism never washed my sins away, but it is a figure of what Christ has done in His death and resurrection. Noah's life is a type of the perfect safety we have in Christ. Now Christ is gone into Heaven and everything in this world is subject to Him.
