Love, in the context of the issue.
So…you have an issue, problem, or something you are concerned about: this is a context, a situation within which you are experiencing stuff.
You may experience doubt, concern, anxiety, fear….
And there is a way to certain success. In NKJV, Romans 28:
28 And we know that all things work together for good to those who love God, to those who are the called according to His purpose. 29 For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren. 30 Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.
Love God. Love God in this situation, in this context.
Discover for yourself: do you have confidence and therefore faith because of the promise? That all things work together for good, to those who love God?
