So are we judging others by which denomination they happen to be attending? The Lord knows those who are His and He is with them.
John 10
11 I am the good shepherd: the good shepherd giveth his life for the sheep.
12 But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep.
13 The hireling fleeth, because he is an hireling, and careth not for the sheep.
14 I am the good shepherd, and know my sheep, and am known of mine. 15 As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep.
16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold,
and one shepherd.
17 Therefore doth my Father love me, because I lay down my life, that I might take it again.
18 No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father.
All of us are at different stages of learning. The time will come when the true believers will know
all truth.
1 Corinthians 13
12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
2 Peter 3
18 But grow in grace, and
in the knowledge of our Lord and Saviour Jesus Christ. To him
be glory both now and for ever. Amen.
