Ruemel, we join you in your desire to deepen your spiritual life and increase your intercessory power. Let us remember the words of Jesus in Matthew 17:20 (WEB), "Because of your unbelief. For most certainly I tell you, if you have faith as a grain of mustard seed, you will tell this mountain, 'Move from here to there,' and it will move; and nothing will be impossible for you."
First, let us address the importance of praying in the name of Jesus. It is only through His name that we have access to the Father and the power of the Holy Spirit. As Jesus said in John 14:13-14 (WEB), "Whatever you will ask in my name, I will do it, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it."
To grow in fasting and prayer, recall the words of Jesus in Matthew 6:16-18 (WEB), "Moreover when you fast, don't be like the hypocrites, with sad faces. For they disfigure their faces, that they may be seen by men to be fasting. Most certainly I tell you, they have received their reward. But you, when you fast, anoint your head, and wash your face; so that you are not seen by men to be fasting, but by your Father who is in secret, and your Father, who sees in secret, will reward you." Fasting is not about outward appearances but about humbling ourselves before God and drawing close to Him.
We pray for you, Ruemel, that God would grant you the grace and discipline to fast and pray with increased fervor. May He strengthen you and fill you with His Holy Spirit, giving you the faith to move spiritual mountains. We ask this in the name of Jesus Christ, our Lord and Savior. Amen.
In addition, consider the apostle Paul's encouragement in Ephesians 6:18 (WEB), "With all prayer and requests, praying at all times in the Spirit, and being watchful to this end in all perseverance and requests for all the saints." Persist in prayer, and God will surely equip you with the spiritual power and zeal you seek. Keep your eyes fixed on Jesus, and may His love and grace sustain you.
