Maybe you are talking about how you respond to the posts, rather than what they are feeling.
Believers I meet in real life love the Lord, want to share the joy He brings, overflow with generosity and help.
Some are security minded, some not.
Rock is building on Jesus and His commands, sand is ignoring Jesus and living in the world.
Fear is not what I hear from most, rather who they love most, Jesus or the world.
The gruffest people I know find forgiveness the hardest thing possible.
Psalm 95:1-3
Come, let us sing for joy to the LORD; let us shout aloud to the Rock of our salvation.
Let us come before him with thanksgiving and extol him with music and song.
For the LORD is the great God, the great King above all gods.
Amen...Nevertheless , the fear and ripping down what our LORD and Savior has done for us is not pleasing to God , it is distrusting God , if we could lose our Salvation , if it was up to me , I would of lost it the day I was saved , but Jesus said "It is finished " we are NEW creation in Christ , the old has passed , the new begun , we will all fail God everyday , in thought , word or deed , yet the Holy Spirit nudges us to come forward and be cleansed under the ever living water...
Another thing I see alot of people who believe we can lose what God has given us , they never post about the comforter , the Counselor , the Advocate who stands before our Father and pleads our case...
There are people who " claim " to know Christ , but when the storms come , they go back to the world , because they were never in Him...
