Matt 7:12 "in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets"
This is the "Will of God" Jesus is speaking of in Matt 7:
“21)Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven"
and in case there was any confusion - it the doers and not the hearers that enter.
"24)Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. 25 The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. 26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand
No one can be a doer of the word unless they are first saved by grace...we cannot obey the Lord without the Holy Spirit first dwelling in us.
Every commandment that we find in the word, that tells us what the standard is to which we must measure up, is the law given as a schoolmaster to bring us to Christ (Galatians 3:24-25).
That no one can keep the law is evident from the following scriptures (and more): Galatians 3:10, Galatians 3:22, Galatians 6:13.
Obedience to the Sermon on the Mount and the Sermon on the Plain, means that when the storms of life come, our faith will not fail...which does not change the fact that our salvation is by grace alone through faith alone in Jesus Christ alone.
Jesus said,
I am the way and the truth and the life: no man cometh unto the Father, except through me (John 14:6)
.
Jesus said,
Ye must be born again (John 3:7).
You must place your faith wholly in Jesus Christ and what He did for you on the Cross in order to be saved.
If you are trusting in your works to save you, then you are not placing your faith wholly in Christ.
If anyone is born again, they will most assuredly be filled with the love of God (Romans 5:5).
Such a love is indeed practical (1 John 3:17-18).
It remains that the way to be born again is through faith in Christ and His finished work on the Cross (1 Corinthians 15:1-4, Galatians 3:14).
