Jesus came to give us a new covenant. Instead of "thou shall or shall not...", the covenant is: "blessed are...". Blessed are you if you recognize you are a sinner because Christ has come to give you the Kingdom of Heaven. The world hated and persecuted the Master and they will persecute you! Rejoice and be glad, for your reward is in heaven. There will be an earthly cost but a heavenly reward. Christ's life was cruciform shaped, ours will be the same. We are called to be salt and light in this life, standing out and being different from the world. When Christians do good works, the glory goes to God.
