Read Matthew 13
The parable of the sower. The path, the rocky soil, the soil with thorns, and the good soil. Are we this soil? It seems that things just are. Faith can change reality. God gives faith, from where it comes I don't know. There is a moment, that someone can say God help my unbelief. From where that comes from I don't know.
Jesus, I don't understand, Give me understand?
Jesus, following you is hard, Give me the strength today to follow?
Jesus, I'm too busy with my life, Give me peace?
I can't argue why things are, but extend that faith in Christ Jesus can change it. Some don't have faith in Jesus, I can't explain why or justify the cause and effect of place and time. All that I can do is pray and trust God that he is just.
