Do not be deceived: God cannot be mocked. A man reaps what he sows. Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life” (Galatians 6:7, 8, NIV).
There’s an old saying, “Whatever goes around, comes around.” When we choose to dwell on evil, we somehow attract it to us and it can destroy us. But when we choose to focus on God’s Word and walk in it, we are pleasing to Him.
