The Father did not require the death of Christ to persuade Him to love us. Christ died because the Father loves us.
The weakest faith gets the same strong Christ as does the strongest faith.
You must know, rest in, think through, and act upon your new identity - you are in Christ
Even those of us who have weak faith have the same strong Christ as others!
If you are justified, you can no more be unjustified than Christ can be pulled down from heaven.
