Scripture tells us...
Hebrews 10:26 For if we sin willfully after we have received the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a certain fearful expectation of judgment, and fiery indignation which will devour the adversaries. 28 Anyone who has rejected Moses’ law dies without mercy on
the testimony of two or three witnesses. 29 Of how much worse punishment, do you suppose, will he be thought worthy who has trampled the Son of God underfoot, counted the blood of the covenant by which he was sanctified a common thing, and insulted the Spirit of grace? 30 For we know Him who said, “Vengeance is Mine, I will repay,” [
g]says the Lord. And again, “The Lord will judge His people.” 31 It is a fearful thing to fall into the hands of the living God.
Matthew 7: 21 “Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. 22 Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’
Jesus has given us everything and asks for so little in return, many do not accept His free gift of salvation but repenting and receiving God's sanctification of all sin and unrighteousness. 1 John 1:9 Our salvation is from sin, not in sin Mat 1:21
