Beware that you do not stop trusting in Christ.

Hebrews 3:12-15

12 So, my fellow believers, be careful that none of you is so evil that you stop trusting in Christ. That would cause you to reject God who is all-powerful. 13 Instead, each of you must encourage each other every day, while you still have the opportunity [IDM], in order that none of you may stubbornly reject God by letting others deceive you (OR, as you deceive yourselves), with the result that you (sg) sin [PRS]. 14 We must encourage one another, because we (inc) benefit from all Christ has done only if we firmly keep trusting in him from the time when we first confidently trusted in him until the time when we die [EUP]. 15 We can do this by paying attention to what the Psalmist wrote in that Scripture passage in which God said,

Now, when you hear me speaking to you(pl) [MTY], do not stubbornly disobey me as your ancestors stubbornly disobeyed me when they rebelled against me.
