How we feel about life depends on our expectations about life.
If we expect life to be all roses and rainbows, then we will certainly be disappointed and frustrated.
That will also affect our relationships with others because we would have certain expectations about them, and that would usually strain the relationships.
On the other hand, when we understand that life is difficult, then we will be prepared to face the struggles and troubles of life.
In the gospel, when the people were full of admiration of Jesus, He said something that is rather astonishing to His disciples.
He said: For your part, you must have these words constantly in your mind – The Son of Man is going to be handed over into the power of men.
Jesus wanted to prepare His disciples to face the harsh reality of life, and He also wanted to prepare them for the reality of the Cross.
Jesus is also telling us that life is difficult, and that we must accept the sufferings of the Cross of life.
When we understand that, then we will be prepared to face the struggles and troubles of life and with the help from God, we will grow in faith and overcome the difficulties.
