You can either accept Jesus' substitutionary death on your behalf, or reject it. If you reject it, you will stand alone before God on the day of judgment and give an account of your life. You will fall short of God's standards [Romans 3:23] and will have to pay the penalty yourself [Romans 6:23] by spending eternity in hell [Revelation 20:15], forever separated from God. But if you accept Jesus as your personal savior, God will accept His sacrificial death on your behalf. It's not a choice you can make on that final day - it's a choice you must make today - either to accept Jesus or reject Him.
God loves you and wants you to spend eternity in heaven with Him. Make the decision today to accept Jesus as your personal Lord and savior. Here's how simple it is.
