Dear sister, I have no doubt in God's keeping power toward us which believe. His grace is not dependent on our faithfulness, and we read in 2 Tim 2:13 If we believe not, yet he abideth faithful: he cannot deny himself. As the body of Christ, we are that part of Him He will never fail.
David said it like this:
Psa 139:1 O LORD, thou hast searched me, and known me.
Psa 139:2 Thou knowest my downsitting and mine uprising, thou understandest my thought afar off.
Psa 139:3 Thou compassest my path and my lying down, and art acquainted with all my ways.
Psa 139:4 For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether.
Psa 139:5 Thou hast beset me behind and before, and laid thine hand upon me.
Psa 139:6 Such knowledge is too wonderful for me; it is high, I cannot attain unto it.
Dear Father, please sustain our Sister
Tristian in ways that passes her understanding, allows her to have the peace You want, and produce the glory of Your work in her. Over and over You have the made the way out of no way for me and my family through the years as You laid out Your paths of righteousness, and great wonder and awe is its product. I'm reminded of the song "Why me LORD," and it is totally Your love that will not let us go. I do pray for her comfort in this storm and give You the praise You deserve in Jesus' name. Amen.
Blessings in Christ Jesus.
