It sounds like you don't have a practice routine. A practice routine helps you develop a pattern for learning new music and playing old music better. Try this:
1. practice your major and harmonic minor scales in every key first right hand then left, then both together - this builds coordination and speed
2. practice root chords with inversions in evey key - this will develop your ear to hearing chords and youe finger placement on the keyboard
3. practice tradtional bass runs to a metronome or drum machine - this will develop your abilty to play in time (very important playing in church)
4. practice adding chord patterns to your bass runs e.g. if your doing the tradtional C, E, F, Gb, G, A, Bb, B, C bass run attach chord like
C / E G A C
E / E Ab Bb C
F / Eb G A C
Gb / Eb Gb A C
G / E G A C
A / E G A C
Bb / D F A C
B / Eb Gb A C
C / E G A C
5. Transpose the above chords in every key. Start slowlly at first then gradually increase the tempo. Onw mistake new musicians make is to learn everything fast like it running away from them.
This should prepare you for learning new music after this warmup.
