No Weapon Formed Against You Shall Prosper

 No Weapon Formed Against You Shall Prosper

...but how does that work exactly?

As I awoke this morning I was imagining a conversation with someone who did not understand that faith is not just believing in something, but it gets up and goes into actions of faith.

I was saying how there is a scripture, "No weapon formed against you shall prosper and every tongue that rises in accusation against you, you shall declare wrong. Isaiah 54:17 continues to say, This is the inheritance of the servants of the LORD, and their righteousness (and vindication) is of Me, says the Lord."

We enter into deeper and deeper levels of trust in God's Word and in God's care for us. When a "weapon" is formed against me, I can (and have) crumbled in my faith that God is able to bring me out of every type of weapon the enemy can "form" against me - sickness, lack, depression, people against me - situations may form against me but they cannot "prosper" - they cannot accomplish what was meant to do to me. Because my trust remains in God that I can go through and come out on the other side prospering in what God is building in me, not in the enemy's efforts to tear me down and dispose of me.

Our mindsets begin to change as we proceed in our lives after we enter into the faith and provisions God makes for us when we become His children. This is the "inheritance" spoken of in Isaiah 54:17 and God says it is because our "righteousness" is derived from our relationship with Him - we are not self-righteous, we come by our righteousness through our salvation by faith in His Son, and in the transforming of our being-like Yeshua/Jesus , which is the work of the Holy Spirit in our lives that we cooperate with.

God never forces us into the transformative state. We can say no and remain just has bad as we were when we got saved, but the "weapons" in life are going to continue to put us in situations where we have to choose - are we going to fight everything the world can throw at us in our own strength or are we going to humble ourselves and enter into greater trust in God's righteousness and vindication?

In the two verses before the beautiful and powerful promise of Isaiah 54:17, God explains: verse 15 declares: Behold, they shall surely gather together, but not by Me: whoever shall gather together against you shall fall/fail for your sake.

For ALL of God's children, know this - people who attack God's children are not acting on His behalf.

Ultimately even attackers, those who mean to bring ANY of God's children harm, will fall. When a child of God under attack grows even more trusting of God's care for them, there is no gathering of attackers that can destroy what God is doing in them - something eternal and glorious.

And here is why. God says that He created "the craftsman" - the enemy of our souls, satan.

16 Behold, I have created the craftsman who fans the coals into flame and forges a weapon fit for its task; and I have created the destroyer to wreak havoc.

Now the devil is the one "who fans the coals into flame" of offense and evil thoughts of destroying God's children. IF A CHILD OF GOD IS OPEN TO THESE THOUGHTS we can be brought into them just as easily as people who have no relationship of care about God. We have to guard our own hearts, what we allow our hearts to embrace, because out of our own heart "flow the issues of life." When our hearts are full on conceit, speaking evil of others, what we despise in others - this is giving our heart over to the devil who is freely fanning the "coals into flame." Once flames rise up, then the schemes begin - forging a weapon to use against the one or ones hated.

God says He created "the destroyer" to wreck havoc. The destroyer is the fallen angel, who is satan and his fallen demons who have the the traits of every evil known to man. They will occupy any heart that gives them welcome entrance, and every one that entertains the demonic traits in their hearts will be vulnerable to worse and worse demonic traits. Even God's children carry places in their hearts they have not allowed the Son of God to prevail over. That is why our lives become our personal battlefield - to overcome the strongholds the enemy had built in our lives, and lay every place within our hearts over to the LORD.

Jesus told His disciples in John 14:30, "for the prince of this world comes, and has nothing in Me." Jesus was tested and tried in every weapon that the "spiritual ruler of this world" has to come against human beings - Jesus went through every trial of His faith in God, and He came out proven as a heart FULL of trust in God.

For instance, in Luke 4:16-30 in His own hometown of Nazareth, when He read from the book of Isaiah passage (Isaiah 61:1-2) about the Anointing of the Messiah, He told them that they were witnessing the fulfillment of that promise of Israel's Messiah.

You must understand "Messiah" in the Hebrew means Anointing. There is no Messianic promise that doesn't bring Heaven's anointing to mankind.

The people understood that this man they knew all their lives was declaring Himself to be the Messiah and that infuriated them. "Familiarity breeds contempt," or as Jesus would say, 'A prophet is not without honor except among the people who are the closest to you—such as friends, family, and hometown neighbors.'

So what happened after that was the "craftsman fanned the flames" against Yeshua among the hometown people "forging a weapon" to use against Jesus.

Having stood on that ground in Nazareth, peering down the steep boulder-filled descent down, imagining the crowd pushing Him toward the cliff from the synagogue, blind with anger, the mob pushing and shoving even each other, I saw how Jesus was not gripped in fear in the midst of all that chaos and havoc. He let them push and shove Him all the way to the cliff, then He walked out of the midst of them in the calm assurance that there was no way God was going to let Him die before He had completed what He was sent to do.

Yeshua was sent to minister - to speak and demonstrate what it looks like to possess a heart devoid of evil but full of God only, in a world where the fallen prince (angel) of darkness ruled over the lives of humankind.

Yeshua/Jesus became the sacrificial Lamb of God in the Great Passover fulfillment. But this is a matter to be told in another post: How God promised The Anointed would come through a promised line of Chosen People who would be given a Land that was to be the eternal inheritance of that people (an inheritance for all they went through to possess it!). Christians often don't know it, but it is the same for us - we go through a LOT to possess our inheritance in Jesus same as Israel has.

Like the Chosen People of Israel, Christians do not enter God's full blessings without rising up and acting on our heart level of trust in God. We don't have everything delivered on a silver platter if we are the people of God in our generation. Acts 14:22 "We must through many troubles enter the kingdom of God."

This is EVERY person's journey to God in His Anointed Son and by the transforming work of His Holy Spirit.
