We are glad to join you in prayer for your three sisters. It is wonderful to see your concern and love for them. Before we begin, we want to remind you of the importance of praying in the name of Jesus Christ. As it is written in John 14:6 WEB:
"Jesus said to him, I am the way, the truth, and the life. No one comes to the Father except through me."
And in Acts 4:12 WEB:
"There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
Now, let us pray for your sisters:
Heavenly Father, we come before You in the name of Jesus Christ, thanking You for the blessings You have bestowed upon our lives. Today, we lift up to You the three sisters of our fellow believer. We pray that You would surround them with Your favor as with a shield, and that Your angels would encamp around them to protect and guide them.
Father, we ask that You would draw them closer to You, and that they would come to know You more intimately. We pray that they would grow in grace and truth, and that Your Holy Spirit would work mightily in their lives, convicting them of sin and leading them in righteousness.
We pray for their relationships, Father, that they would seek godly spouses who fear You and walk in Your ways. We ask that You would prepare them for godly marriages and that they would wait upon Your timing.
If they are struggling with anything, Lord, anything that is outside your will. We pray that you would convict them and empower them to change. May they know Your will for their lives.
We ask these things in the name of Jesus Christ, our Lord and Savior. Amen.
Be encouraged, dear believer, knowing that the effective, fervent prayer of the righteous accomplishes much (James 5:16 WEB). Trust in the Lord, and He will act on behalf of your sisters.
If your sisters are not yet believers in Jesus Christ, then pray for their salvation. Remember it is written in Romans 3:23 WEB:
"For all have sinned, and fall short of the glory of God."
And in Romans 6:23 WEB:
"For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord."
And in John 3:16 WEB:
"For God so loved the world, that he gave his one and only Son, that whoever believes in him should not perish, but have eternal life."
If your sisters are already believers, then pray for them to continue in the faith and to grow as Christians. Remember it is written in 1 Peter 2:2 WEB:
"As newborn babies, long for the pure milk of the Word, that with it you may grow."
And if your sisters are Christians already, remind them of the scripture in 2 Corinthians 6:14 WEB:
"Do not be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?"
Encourage them to seek a spouse that is a fellow Christian believer. And finally, pray for them to keep themselves pure and holy until marriage. As it is written in 1 Thessalonians 4:3 WEB:
"For this is the will of God: your sanctification, that you abstain from sexual immorality,"
