There is no greater Kingdom work than that given in the great commission.
Our job as Christians therefore is simple; to get others (unbelievers) to know the Father, and to believe in Him through Jesus Christ. And to be a continuous source of inspiration to other believers through our love and faith walk.
Any activity directed at getting people into the Kingdom of God is the Father’s Business.

a sound mind is a mind that is at peace; free of worry, fear, anxiety. A mind capable of good and rational thinking thinking. A wise mind.
Jesus gave us peace. He gave us His peace. The seed of peace was planted in our spirit when we got born again. We are to let the fruit of this seed rule us.

Kings reign and rule through words. Their decrees become established and they govern their domains through them. Kings give commands and processes are immediately set in place for actualization of such commands. Kings rule through words.

A shepherd is someone who tends and rears sheep. A shepherd caters for the sheep. A shepherd has a responsibility to guide, protect and provide for the sheep. So in a sense, the shepherd watches over the sheep and the sheep is fully dependent on the shepherd.

There is therefore a strong bond that exists between a shepherd and a sheep. The shepherd loves the sheep and expresses this love in the level of care given to the sheep and in return, the sheep trusts and relies on the shepherd.

Jesus describes Himself as the Good Shepherd, which He quickly contrasts with a Hireling (a hired hand, who is not the owner of the sheep). From the way Jesus sees it, a shepherd is considered ‘Good‘ when he can go to any length (including losing his own life) to care for the sheep (John 10:11)

We don’t need any other Shepherd dying for us, Jesus already did.

Below I share Psalms 23:1‭-‬6 from the Easy-To-Read version. I pray that it is a reminder to us all, that Jesus is truly committed to caring for us. As you read this Psalm today, consider and assume the position and confidence of its writer….

The Lord is our Shepherd; He watches over and caters for us……..

The Lord is my shepherd. I will always have everything I need. He gives me green pastures to lie in.

He leads me by calm pools of water. He restores my strength.

He leads me on right paths to show that he is good.

Even if I walk through a valley as dark as the grave, I will not be afraid of any danger, because you are with me. Your rod and staff comfort me.

You prepared a meal for me in front of my enemies. You welcomed me as an honored guest. My cup is full and spilling over.

Your goodness and mercy will be with me all my life, and I will live in the Lord’s house a long, long time.

So a sign is usually indicative of something and is often looked out for. For example, a rainbow may indicate changes in season, a thunder may signal a coming storm.
If believers are to lay hands on the sick to recover, then there is healing power in a believers hand (in the name of Jesus). But how best to prove this except by acting on it.

I will give you the keys to God’s kingdom. When you speak judgment here on earth, that judgment will be God’s judgment. When you promise forgiveness here on earth, that forgiveness will be God’s forgiveness.”
Matthew 16:19 ERV

So Jesus is saying to us to regularly announce, tell, declare, to make a show of, to lift up the banner of victory He purchased with His blood, to raise it high, to wave it high, to not be silent about it…… Since partaking of the communion is obviously not a loud event (physically), this proclamation/declaration is  something like a silent noise

What we do with the promises of God is to claim them. So the next time you sing this song, carefully make it into a confession, that Jehovah is the God who heals you, He sent His Word and healed all your diseases. That is the right Spirit with which to sing that song.

[Then] He will cover you with His pinions, and under His wings shall you trust and find refuge; His truth and His faithfulness are a shield and a buckler.
Psalm 91:4 AMPC

If My people, who are called by My name, shall humble themselves, pray, seek, crave, and require of necessity My face and turn from their wicked ways, then will I hear from heaven, forgive their sin, and heal their land.
