Our mother recently passed away. She believed in Jesus as her Savior, so we know her soul is in heaven with Him. We miss her terribly but rejoice for the end of her earthly suffering and the beginning of her eternal joy. Is it inappropriate or otherwise questionable for us to pray to Jesus to let our mom know how much we love her, miss her, and look forward to seeing her again in heaven?
I sympathize with you at the death of your mother. As Christians, we do deal with the sorrow of temporary separation from our loved ones. At the same time, we praise God for bringing them into his presence in heaven.
The Bible calls those who die in the Christian faith “blessed” (Revelation 14:13). Christians who die and enter the presence of God in heaven are blessed in that they are forever free from sin and its effects (Revelation 7:16-17). Christians in the presence of God in heaven are enjoying perfect peace and joy.
For those reasons, there is no need to try to get messages to Christians in heaven. They do not need encouragement or reassurance of any kind.
On the other hand, we—the survivors on earth—need encouragement as we continue to “fight the good fight of the faith” (1 Timothy 6:12). Thankfully, in the gospel God provides the encouragement and the strength we need.
In the Bible God also informs us that on the Last Day he will bring together all his followers (1 Thessalonians 4:13-17), and they will never be separated. Then he tells us: “Therefore encourage one another with these words” (1 Thessalonians 4:18). Let’s continue to do just that.
