Jeremiah 5:25 Your iniquities have turned away these things, and your sins have withholden good things from you.
God has great things for His people but if we choose sin over Him then we suffer the consequences. I think that we see sin as small while God is telling us that much of the junk happening in our lives is a result of our hindering His blessings on us. We choose sin. Choosing sin means that we loose His blessings.
How many good things are you missing out on because you choose sin over God? How much is your marriage harmed because you do not choose to obey, serve, and seek after God? You are missing out but it is your own doing!
