AI OVERVIEW: Assurance of salvation enables confident, direct prayer to God, because faith in Jesus means eternal life begins now and grants access to the Father. Prayer is a two-way conversation—speaking to God and listening for his guidance—rooted in relationship, Scripture, and walking with him, with requests aligned to his will. God answers prayer in four ways—yes, no, delay, or different—and each can serve his good purposes, as illustrated by Peter's jailbreak (yes), Paul's thorn (different), Lazarus's death and resurrection (delay), and Müller’s hunger for provision (yes in practice). Interceding for others strengthens the body: praying for a believer who sins to restoration, confessing sins directly to God, and standing in the gap for one another until all are walking in vitality.
