Jesus did not die on the cross so that you don’t have to obey God and keep his laws.
Salvation is truly a gift of God, no argument there. But of late I’ve heard two teachers (one on Twitter and one on CBN) say that you don’t have to keep the law and salvation is not because of obedience. These statements are simply not true.
Romans 6:23 KJV For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
You can’t disregard the first part of this verse and accept the second. The wages of righteousness is salvation. Conversly, if you continue in your sin, you will die. To say it plainly this means spiritual death. You will not enter Heaven, your eternal destination is the lake of fire.
