Ever said or felt "I've waited so long and nothing seems to be happening...."?

I woke up yesterday thinking about how it seems I've been waiting for God's promises so long and they don't seem to be working out. I've had struggles with work stuff and other things that seem to go on. This morning I noticed an anger towards the preaching. The scripture was fine but after thinking about it I realized a bitterness growing in my heart because of delays. I skipped communion as I needed to get my heart right and after getting prayer I had a friend suggest spiritual warfare as the main cause of delays. I prayed with another friend and went home and prayed. I turned on the live stream of the International House of Prayer and this is what they soon began to sing (partial transcript):

Do not worry, or fret because of evil doers

Look at Jesus how he lived in hiddeness

Years and years of obedience in hiddeness

So many years of pursuing your heart

Why do you lead like this

Do not worry or envious of the wicked even though they seem prosperous

Everything is not as it seems

Where you sow you know you will reap

Give it time

You got to give it give it time

No, I’m not in a hurry

I’m looking for obedience not impact

I’m looking for obedience not results

Are You learning to love?

Be patient young man

Be patient young women

Says the Lord

Stay steady, persevere

Patience having it’s perfect work in you

Sometimes waiting produces something nothing else can do

Be patient

Look unto Jesus

Because he waited

I will wait

Consider him who endured such hostility from men

Setting my eyes on Jesus

Help me, help me God

My son do not lean on your own understanding

Trust me, do good

You just keep walking the narrow way and leave the results to me

Just you wait and see

Trust in the Lord and do good

Trust in the Lord, do not quit, do not give in

He’ll take care of the rest

He can see the end from the beginning

He is faithful to complete what he sarted

The kingdom of God is like a seed that has to go down and be invisible for awhile

There is so much going on that you can’t see

Behind the scenes

I know how to lead my sheep

I will lead you well

Trust in me and do well

I am doing things that you would not even believe

You’ve got to trust me

Blessed are those who do not see and yet believe

So much growth going on behind the scenes

There’s a blessing when you don’t give up

There’s a blessing when you don’t give in

Over time you will receive

Reaping fruit for eternity

Do not stop doing good

The fruit will come for us

If you ever hate life or get discouraged in your walk with God don't give up! Keep your heart free from bitterness and trust God. I get it, it's tough. Jesus understands it too. Don't listen to voices that say there's some quick way. This has always been how it's been. Don't give up. There will be fruit. Psalm 73
