Not under old law again for half of your points ..... Being a faithful Christian isn't easy and there are lots of rules (all are instructions for a perfect life) but we knew its not easy by Matthew 7:13-14 but it is not impossible and it is not grievous
1john 5:3
Jesus said His yoke is easy.
There aren't any rules.
The instruction is for learning how to grow in grace and the knowledge of the Lord, but only Jesus lived the perfect life, and reckons it as ours as a gift.
The psalm is under Old law ..... 1corinthians is saying "if I come in a language you don't understand what good does it do, or if you go to war and the trumpet doesn't make its correct noise how will you know to attack?" (Paraphrasing of course) but it isn't discussing worship .... And revelation is being metaphorical (four horseman and such)
Do you Really Really want to be under all this religious bondage and law-keeping?
Do you like the restrictions that are put on you?
If so, go ahead, but you'll get no converts here, so you may as well head on.
But if you're not feeling right about about that hammer coming down on you, we are here to help.
Jesus loves you, and is not mad at you, He didn't come to condemn you, but to save you and set you free.
If you feel stuck in a legalistic church, and want to be delivered from it, consider it done. Simply walk away.
Ask the Lord to show you where He would have you go so you can honestly worship Him from the heart in spirit and in truth, like you know your soul is crying out to do even now.
Ask our heavenly Father for the Holy Spirit, ask Him to open your eyes and heart to see the great salvation He purchased for you with the shedding of His own blood on the cross.
Ask Him to let you see into a tomb that is empty, and realize the devil couldn't beat Him, the grave could not keep Him, your sin has been washed away, He is risen and alive forevermore, and eternal life with Him in His kingdom is His gift to you.
Sing, shout, dance, play an instrument, laugh, cry, praise the Lord with all your worth, and rejoice because He wrote your name in His book of life.
Freely you have received, freely give, your whole heart, soul, mind and strength, for worthy is the Lamb who was slain to receive all honor and praise! He's the God of love, peace and joy, don't let anyone rob you of it.
