As Christians we are to be salty in bringing the word of God to other people, by letting our light shine. Salty meaning we are to not be afraid of what other people will think of us. Our Light is the word of God. That we should bring glory to God by not being shy about spreading the Word of God to people who may not have a relationship with God.
We have glory when we have a good relationship with our Lord, but at the same time we will see suffering at the hands of non-believers who would rather not see our light shining.
If all people had the same belief in the Lord as was intended by God, Jesus suffering would not have been necessary. We do not all believe in the same God. Some even have false idols. Therefore Jesus suffering was necessary. God had to make a bold enough statement thru Jesus to show non-believers that he was very serious about saving all the sheep in the flock. And in the same way our suffering is also necessary. When you step out in faith and spread the Word of God there will be those who mock us thus suffering.
Churches across this nation are filled with people every Sunday. But do these same people live the Word of God everyday or just on Sunday? Romans 12:2 says not to conform to the ways of world. Therefore we are to be Christians everyday of our lives not just on Sunday. Sunday Christians only want to be seen on Sunday and then are not salty and hide their light under a bowl the rest of the week. Love the Lord with all your heart, soul, mind, body. Let your light shine, be ready for the love of God to be seen through you.
