Life being life, and we being fallible and sinful human beings, we all must suffer one of two pains: the pain of discipline or the pain of regret.
We can choose willingly to fall under the loving and firm guidance of God and suffer through the discipline of becoming the people we were created to be. Or we can choose to live life according to our own ways and live life to our own song and suffer the pain of regret.
That we make mistakes along the way, that we stray, that we err is a certainty. This is part of what it means to be a fallible and sinful beings. No one will ever live a perfect life. But should we choose to follow hard after God, God will never disappoint us.
While we must all suffer either the pain of discipline or the pain of regret, the difference is that the pain of discipline weighs ounces and endures for a moment, the pain of regret weighs tons and can last forever.
The choice is up to us.
