Trials and tribulations will come, one who is known to others as a fair weather Christian are ones that turn away as soon as diverse trials come upon them, they think the Christian life is nothing but joyous. Christ suffered and so will we. There will also be happiness in our lives but we will face difficult challenges, so don't give in. It will be all worth it in the end. Take a look at the psalms for instance, they are not all positive in meaning, although through it all they still praise God. The fair weather Christian is also depicted in the parable of the Sower which is on thorny grounds, or maybe stony grounds which do not progress or are choked out of it.
