Samuel 23:8-10
8 These are the names of David’s mighty warriors: Josheb-Basshebeth,  a Tahkemonite, was chief of the Three; he raised his spear against eight hundred men, whom he killed in one encounter.

9 Next to him was Eleazar son of Dodai the Ahohite. As one of the three mighty warriors, he was with David when they taunted the Philistines gathered at Pas Dammim for battle. Then the Israelites retreated,

10 but Eleazar stood his ground and struck down the Philistines till his hand grew tired and froze to the sword. The Lord brought about a great victory that day. The troops returned to Eleazar, but only to strip the dead.

1. You become what you practice.

Philippians 4:8-9
8 Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things.

9 Whatever you have learned or received or heard from me, or seen in me—put it into practice. And the God of peace will be with you.

2. Confidence is found is practice.

Hebrews 13:6
6 So we say with confidence, “The Lord is my helper; I will not be afraid. What can mere mortals do to me?”

3. It's Easy to practise what you love. 

1 Corinthians 16:13-14
13 Be on your guard; stand firm in the faith; be courageous; be strong. 14 Do everything in love.

4. Be careful what you love.

1 Corinthians 6:12
12 “I have the right to do anything,” you say—but not everything is beneficial. “I have the right to do anything”—but I will not be mastered by anything.
