“For you shall eat the fruit of [the labor of] your hands, You will be happy and blessed and it will be well with you.”
Whatever effort you sow into God's way of life is the best investment anyone could ever do. God will not be out given. The heart and mindset is to keep His promises.
When you obey and believe, even when it’s hard to do either one, you show God that you trust Him.
It is then you will see Him.
Every action taken is a seed sown, and for every seed there is a harvest. You will be happy and satisfied. God’s promises are yes and Amen.
If He promised, He is faithful and true to keep all of His promises.
