The narrow gate!
In life we see practically every day that the path is very difficult, God proposes that we enter through the narrow gate.
This means that the most difficult path, the path of goodness, of love, a life that manifests the love of Christ everywhere. That narrow gate is Christ. Only through him do we have access to the Father.
Enter through the narrow gate; for wide is the gate and broad is the road that leads to destruction, and many are those who enter through it; 14 because narrow is the gate and difficult is the road that leads to life, and few are those who find it.
Matthew 7:13-14
