Our survival is governed solely by a simple but fundamental principle. Humanity in every place and in every age and of every religion is subject to its command. No exceptions. Only by including God in our lives do we live and only by excluding God from our lives do we die. To include God in our lives in the hereafter, we must include God in our lives now! By excluding God from our lives now, we exclude God from our lives in the hereafter. Take an interest in God and God will take an interest in you. Include God in your life and God will include you in theirs. Ignore your God and your God will ignore you.
The attitude that sinners need to adopt is the attitude of new born birds in the nest clamoring at their parents for food - the attitude of asking, seeking and knocking. And, perhaps, a thank you when a blessing comes your way.
