Do you have a biblical justification for that viewpoint?
Good luck with keeping that in its entirety. ‘God’s word as set forth in scripture’ See also the above for the odds on a man or woman keeping God’s Law. You have already failed. See the above for finding salvation in the Law, it isn’t there. Luckily, you can also find the path to salvation in the above as well.
You're exactly right. Trying to find salvation by following God's law WITHOUT the indwelling spirit of Christ is an exercise in futility. However when Christ indwells in us his righteousness makes up for our shortcomings. But we still let his spirit guide our lives. We conform our lives to his will, which is expressed in scripture. Christ observed Passover and told his disciples to do the same.
’ Trying to find salvation by following God’s law WITHOUT the indwelling spirit of Christ is an exercise in futility.’
Yet even when Christ dwells in you, you still sin. Christ’s perfection, not our own is the basis of our salvation. In place of the Passover, I’ll take the Lord’s Supper. The Lamb of God is in the latter is identified, not represented by an animal.
‘Enjoy your Passover then. Legalism is defined in following God’s Law.
Do you have a biblical justification for that viewpoint?’
Perhaps I should have added ‘tradition’ as well. Jesus healed on the Sabbath. Agin the ‘Law’. Gal Ch 3, has a fine discourse on the subject, 19 and following.
