Why are Christian Contraception Couples public enemies of God?

The Church is triumphant, it declares the Resurrection to the world. Her architecture imposes itself on the city, Her bells wake up the apostates every morning, Her priests in robes send a message that there is something higher, Her Crosses decorate the skies and homes, Her married children say - “Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they?” (Matthew 6:26). Indeed, if the married Christian Couple enjoys prostitution within marriage (Contraception), a non-believing family next door will say - Look at these Christians, they are just like us, afraid and selfish. What do they have that we don’t? Do they have peace that their Lord has promised to them? Do they have courage of their martyrs? Do they believe that God will take care of their family? Or they have to use contraception that we infidels have perfected for them? Did their God design them poorly so they have to be careful? Who are these hypocrites? Why they ring bells, just to annoy us non-hypocrites?
