Decide now. Tomorrow might be too late. The salvation of your soul from Hell is the most important thing to have before your life ends. After death shall be the judgment (Heb. 9:27), and there will be no more chance ever be given again to you after all.
Rom. 6:23 reads that the punishment of sin is death; not only of your physical body but also of your soul in Hell. Since all have sinned (Rom. 3:23), all will go to Hell. But God expressed His love toward us (Rom.5:8) so that we would never suffer in Hell (Jn. 3:16) but would live with Him eternally in Heaven someday (Jn. 14:1-3).
Now is the accepted time. (2 Cor. 6:2) Death comes as one of life's greatest surprises. Repent to God and believe on the Lord Jesus Christ (Acts 20:21).
