The acronym T.U.L.IP. is the Gospel of God's Grace in Christ:
T - Total Depravity (Radical Corruption; Jer. 17:9)
U - Unconditional Election (Sovereign Election; Rom. 9:11)
L - Limited Atonement (Particular Redemption; Mat. 1:21)
I - Irresistible Grace (Effectual Election; Ezek. 36:26-27)
P - Perseverance of the Saints (The Preservation of the Saints; Rom. 8:30; 1Pet. 5:10: Jude 1:24-25)

Like I said, you believe in an acronym. Believe the Gospel;
1 Corinthians 15:1-4 New American Standard Bible (NASB)
1 Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand,
2 by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain.
3 For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures,
4 and that He was buried, and that He was raised on the third day according to the Scriptures,
Now isn't that easy. The gospel was never meant to be difficult.
