How you end a letter varies depending on the addressee, the sender, the purpose and the style of the letter. If your Christian faith is important to you, you might want to share God's love by including a blessing. Perhaps the recipient is a non-Christian, and you want to share your faith, or maybe he's a fellow believer, and you want to send a Christian greeting that means something to both of you. There are no hard-and-fast rules for signing a Christian letter, but some basic Christian and letter-writing principles can guide you.
Sign an informal letter with the traditional Christian greeting "God bless," followed by your signature.
Use a more explicitly Christian greeting, such as "The Lord Jesus bless you," if you know the other person is a Christian believer.
Identify yourself as a fellow Christian by signing a letter "Yours in Christ," "Your brother in Christ" or "Your sister in Christ," followed by your signature.
Use a biblical greeting for a formal letter with obvious religious content. For example, use or adapt a Bible verse such as 2 Corinthians 13:14, which reads: "May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all." Alternatively, shorten it to "The grace of Jesus Christ be with you."
Sign a letter as you would normally, but include a favourite Bible verse after your signature. Choose something short and positive, such as Psalm 136:1: "Give thanks to the Lord, for he is good. His love endures forever."
Express your Christian joy in your own words. A sign-off need not be wordy and impressive. "Peace and joy," "Thoughts, hugs and prayers" and "Wishing God's best for you" are a few examples of informal Christian blessings you can write before your signature at the end of a letter to a friend.
