You are either walking in curses or blessings.

“Like a flitting sparrow, like a flying swallow, So a curse without cause shall not alight.” ‭Proverbs‬ ‭26:2‬ ‭NKJV‬‬

Every sickness or disease is undoubtedly not a blessing. Ask the Lord what the cause is. Many in the church believe in blessings but tend to ignore the curses identified in Deut 28.

There is a cause for every curse. Deut 28:45-47 identifies Two reasons: because you did not obey the voice of God, to keep His commandments and statutes and because you did not serve the Lord your God with joy and gladness of heart.

Curses can also be generational (Exodus 20:5-6, 34:6-7; Numbers 14:18; Deut 5:9).

There is a remedy: Confess your sins and forefathers and thank Jesus Christ for redeeming you from the curse according to Galatians 3:13 and loose blessings to you.
