A lack of faith is a sign of a weak prayer life. Jesus Christ advises us how to address unbelief—prayer and fasting.

On a human level, how do we build trust, faith, and loyalty? Will we have faith in someone we do not know? Can we be loyal to a stranger? We build confidence in others through repeated contact with them over time—close and frequent communication. As we get to know them, to see them in action, to see their characters, we eventually reach a point where we can have trust and faith in them and in their behavior. Is it any different with God?

Prayer provides the repeated and continual contact with God that we need to get to know Him. This sets in motion the process that will lead to faith, to God being willing to give us the gift of faith (Ephesians 2:8). The prayerful person becomes the faithful person, not the other way around. Hebrews 11:6 illustrates this point: "But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him."

Notice the condition in this verse: God is not the rewarder of everyone, but "of those who diligently seek Him." The gift of living faith comes from diligently, actively seeking Him, consistently and with zeal. Prayer is a major tool in seeking God, along with study, fasting, and using the knowledge gained to conform to His will—practical Christian living and overcoming. Those who prove their diligence by doing these things are the ones rewarded with the faith to overcome (I John 5:4).

The Sabbath is an external sign that identifies God's people (Exodus 31:13, 17). Yet a person may be a nominal Sabbath-keeper without having a true relationship with God. Is there another sign—a less visible one—that perhaps only God sees? Yes, and Zechariah 13:9 shows it is prayer: "They will pray in my name, and I will answer them. I will say, 'You are my people,' and they will reply, 'You, LORD, are our God!'" (Contemporary English Version).

Those with a weak prayer life have weak faith (Matthew 17:19-21). Those with weak faith are sinful (Romans 14:23) and are promised death (Ezekiel 18:20; Romans 6:23). That is just how important earnest prayer is as part of a solid foundation, especially during the end time. As I Peter 4:7 instructs, "But the end of all things is at hand; therefore be serious and watchful in your prayers."
