Think on this... your prayers never, EVER, expire! Isn't that amazing?! Ponder on the fact that when you have said your goodbyes on this earth, that your prayers still linger and Christ continues to intercede on your behalf. This ought to make us more determined to never take for granted the power and the lingering presence of prayer.
It has been said that “prayer moves the arm that moves the world;” and if there is anything that can prevail with God, it is prayer - humble, fervent, earnest petitioning.
- Albert Barnes
The effectual fervent prayer of a righteous man availeth much. James 5:16c
