I can tell you that God is alive because I talked to him this morning.
I don't think I get angry.
'God is Love' means that He tries constantly to block your route to destruction.
God does not change - and neither does His love. He loved you before you were born... He loves you now... and He will love you forever.
You cannot build a superstructure on a cracked foundation.
Don't be a half-Christian. There are too many of such in the world. The world has a profound respect for people who are sincere in their faith.
