"Sacrificing and offering Thou didst not desire; mine ears hast Thou opened..." (Psalm 40:6a)
"And He took him aside from the multitude, and put His fingers into his ears, and He spit, and touched his tongue; And looking up to Heaven, He sighed, and and saith unto him, Ephphatha, that is, Be opened. And straightway his ears were opened..." (Mark 7:33-35a)
The first part of the opening line of the next verse says "And he charged them..." But it's not talking about money. He tells them not to make it known what He just did. Because, until you're strong enough to maintain what Jesus gives—and gives freely, I might add—best to keep your mouth shut. Your ears may be open but the only person to speak to about it is God. This is not an uncommon occurrence. As God should be the One with whom we converse and are conversant, everyone else should fall by the wayside until the former is met. With reference to ceteris paribus (with all things equal) until the atmosphere abroad is ready, rejoice that you're able to hear.
"And when He had said these things, He cried, He that hath ears to hear, let him hear. And His disciples asked Him, saying, What might these parables be?" (Luke 8:8-9)
"And He said, Unto you it is given to know the mysteries of the Kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand." (Luke 8:10)
People see it all. They really do. It's the condition of our heart that tells whether or not we're going to be seeing it correctly. The difference between seeing what's there and missing something is looking. Try this on: Paul says to Titus (1:15), "Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled." If you couple this with his instruction to "overcome evil with good." (Romans 12:21) The way we see things depends on how dialed in we are to God. To where we see Heaven here on earth.
"Multitudes, multitudes in the valley of decision: for the day of the Lord is near in the valley of decision." (Joel 3:14)
The Hebrew word translated decision is "charuwts". Strong's says "properly incised or incisive". The word (decision) appears twice in the Bible (it's also translated as "gold" in numerous places, see Psalm 68:13). A Hebrew word for "distinguish", however, is "biyn". In Psalm 5:1, David asks God to "consider my meditation". He's asking God to sift through his internal processes to where they're springing from a true source (a true vein as it were). We have no idea the mercy of God dispensed as a result of wrong thinking and the havoc it wreaks on the world. On, off. Trust and faith and belief. And love. Or not. If you believe in God and want to speak on His behalf, you might consider praying this prior to opening your mouth:
"Let the words of my mouth, and the meditation of my heart, be acceptable in Thy sight, O Lord, my strength, and my redeemer." (Psalm 19:14)
