Maybe a tape, book, scripture, video, or just a card or an expression of gratitude for them. First problem is to keep moving upward from hope to faith for them. Flesh hopes, spirit believes. Even though the answer delays keep praising Him because He is always working His purpose out. The longer the delay the more strength and encouragement they will need.
Prayer is our responsibility.
Pray for the lukewarm and disinterested and those that hurt us. One of the common problems facing the church is this problem of failing to continue to move forward with God. We can't stay still. We either are going forward or we are going backward. Even though God desires ALL men to be saved He will still deal with us through these people until they receive the light to make a proper decision and commitment.
